32 Mark schemes Q Material sliding down a slope mass movement Particles of sand are bounced along the beach transportation Temperatures rise above and fall below 0 C causing water to freeze and ice to thaw weathering AO1 1 AO2 2 [3] Q A change in both the appearance and the mineral composition of rock. chemical The effects of plant roots or burrowing animals on rock. biological The breaking of rock into smaller pieces without changing its composition. mechanical AO1 3 [3] Q3. Weathering can weaken the coast making it easier to erode. Changing temperatures around 0 degrees will lead to freeze thaw weathering and pieces of rock will be ready to break off if hit by the waves. Changes in temperature with a lot of heat during the day and less at night will lead to similar effects. Some rocks such as chalk and limestone allow water to enter them and so they are susceptible to freeze thaw weathering and they are also soluble in rainwater. 2 1 for basic statements; for a statement that is elaborated. AO1 1 AO2 1 [2]

33 Q4. All correct = 2; 1 correct = AO1 2 [2] Q5. All correct = 4; 3 correct = 3; 2 correct = 2; 1 correct = AO1 4 [4] Q6. The sea erodes the coast via hydraulic power which is the sheer force of the water on the coast (1); abrasion where material being carried is hurled at the cliffs (1) and this acts like a sandpapering effect (1); attrition where material being carried knocks into other rock fragments (1) and they become smaller / more rounded (1); solution where certain rocks such as chalk and limestone (1) dissolve in sea water (1). Swash / backwash stronger backwash removing beach material. 3 1 AO1 3 [3] Q7. Swash Longshore drift

No credit if two or more answers shaded. AO4 = 1 (c) Accept reference to the effect of: direction of dominant waves (1) differences in offshore gradient (1) differences in rock type and gradient, e.g. some rocks are stronger than others resisting wave attack (1) structural differences, e.g. faulting and jointed structures (1). Answers must apply understanding of coastal factors to interpret the resource. No credit for description of the coastal features or for explanations relating to different types of waves. AO3 = 1 (d) One mark for the correct answer: B North west. No credit if two or more answers are shaded. AO4 = 1 (e) The process only has to be named.

AO1 = 1 [5] Q9. (a)

35 3 1 AO1 1 AO2 1 AO3 1 3 (b) Waves erode the / face of the cliff. An important erosion process is longshore drift / A / bay is formed. Continued erosion causes an arch to form. This retreats / to leave a sea stack. 4 1 AO1 3 AO2 1 4 [7] Q10. (i) 1 mark = 1 correct 2 marks = 2 correct 3 marks = 3 correct 4 marks = 4/5 correct Arch Headland Cave (accept sea cave) Stack Wave-cut platform (w.c. platform) 4 (ii) Level 1 Basic (1 3 marks) Basic understanding of process (names of processes with no real explanation) and incomplete sequence (individual features). The sea hits the cliff and it is eroded forming caves and arches. Eventually the arch gets bigger and collapses leaving a stack. Level 2 Clear (4 5 marks) Some clear link between processes and features and an understanding of the sequence of erosion (link between features not all features required). The force of waves hitting the bottom of the cliff causes cracks and caves to develop. The waves carry sand and this speeds up erosion when it hits the cliff. Where land sticks out into

36 the sea, the caves on each side break through to form an arch. With continued erosion, the arch collapses, leaving a stack. 5 [9] Q11. (i) X swash / approach at an angle; Y backwash / goes back at right angles, straight down beach; Z direction of movement of material / longshore drift. or any valid descriptive alternative for each AO1 1 AO2 A AO3 1 (ii) Any 2 spit, bar, beach, tombolo, cuspate foreland AO1 2 [5] Q12. (i) Groyne (accept incorrect spelling as long as clearly referencing a groyne). 1 (ii) 1 mark for a point about each zone (not comparative statements). A wide beach/beach at angle or zig-zag/triangular/angular or diagonal/slanted/observation about unevenness linked to groyne B narrow beach/straight beach/thin/fairly even with jagged edge. 2 (iii) 2 1 mark for single point At A the groynes trap the beach material/protect the beach (1) Not much beach material gets to B because of the groynes at A (1) A is protected, B is not (1) 2 marks for developed point In Zone A the beach is wider because it is protected from longshore drift by groynes which trap the sand. 2 (iv) Because of the town, etc (max 1 mark no reference to the idea of protection). Because of longshore drift (1), to preserve the beach (1) To protect build environment (1) such as (town, holiday centre, main road) (1) To protect the town (1) without defences the area would be

37 threatened (flooding, erosion) (1) Because it is a holiday centre where the beach (1) needs to be protected (1) Because of the town/holiday centre (1) which is valuable (1) 2 [7] Q13. (i) These waves have crests a long way apart - constructive These waves are steep - destructive These waves are more frequent - destructive AO1 3 (ii) Content will depend on case study used. Expect reference to Norfolk coast such as Happisburgh, Barmston, Mappleton in Holderness and Barton-on-Sea, Hampshire which is example in endorsed textbook. Reference likely to be made to exposed nature of coast and length of fetch giving rise to powerful waves; the rock type that is often soft and easily eroded and undermined; the presence of different rocks with permeable sands on impermeable clay encouraging instability; the presence of buildings adding weight to the cliffs or use by people, e.g. footpaths; the presence of streams (Barton) or very heavy rain (Holbeck Hall Scarborough). There may be reference to the vulnerability of the base of cliffs and possible reference to the impact of coastal management especially groynes and areas further along the coast being starved of beach material. Level 1 (Basic) 1-4 marks Simple points, may be list like. Generalised, applicable to anywhere where cliff collapse is an issue. Statements may be in a random order. Ideas are separate. Waves are big and powerful. They have come from a long way. The cliffs are made of soft rock. People make groynes along the coast and interfere with it. This makes cliffs collapse. CMI annotation L1 Simple points generic L1 Begins to explain has a variety of points Level 2 (Clear) 5-6 marks Points are developed and linked. Clear sequence; explanation is focus. Refers to case study points relate to case study quoted. The Holderness coast is exposed and waves travel a long way across the North Sea to reach it. The large fetch makes the waves powerful and able to undercut the cliffs. The cliffs are made of boulder clay in many areas and is

38 soft and easy to erode. At Mappleton, rock groynes have been put in front of the cliffs to stop erosion and at right angles to them. This stops the material moving down the beach and increases the erosion at places such as Great Cowden. CMI annotation L2 Clear focus on explanation. Develops/ links and refers to case study 6 AO1 3 AO2 3 [9] Q14. Any 2 valid differences relating to the frequency, steepness, height, relative importance of swash/backwash. [2] Q15. Mass movement occurs when loose material on the land surface (1) moves downslope (1) due to gravity (1) sliding and slumping (1). This is often fast and sudden (1) as with landslides (1) when the base of the cliff has been eroded, making the cliff unstable (1). With a landslide, the whole column of material moves in one go (1), slumping is similar, but this involves a curved movement (1). 3 1 AO1 3 [3] Q16. (i) Erosion Weathering Transportation Deposition 1 correct = 1 mark 2 correct = 2 marks 3-4 correct = 3 marks 3 (ii) C A (2 x 1) 2 (iii) Saltwater lake Salt marsh Neck of spit Mudflats Recurved end 1 correct = 1 mark

39 2 correct = 2 marks 3 correct = 3 marks 4-5 correct = 4 marks 4 (iv) Identify key points which illustrate the process of movement and deposition. - Any idea about material being carried/moved (1) - name of process longshore drift (1) - links to the shape of the land (1) - any idea about material being deposited (1) - waves/currents reshaping the land (1) 4 [13] Q17. (i) 4 x 1 A headland (accept type of headland) B cave C arch D wave cut platform 4 (ii) Level 1 Basic (1 3 marks) Some basic understanding of process but limited technical detail. The stack used to be part of the cliff but the sea has worn it away until the top of the cliff has collapsed, just leaving the stack which is now separate from the main cliff. Level 2 Clear (4 5 marks) Clear awareness of correct sequence and some appreciation of technical detail. Clear, correct sequence and some process (4) Clear, correct sequence and process (5) Hydraulic action has eroded a cave in the cliff which has got bigger over time forming an arch. Eventually the roof of the arch has collapsed, leaving an isolated piece of rock which is the stack. 5 [9] Q18. Level marking Level 1 (1-2 marks) Basic statements.

40 E.g. Stop the waves, trap sand, stop erosion, absorb wave energy. Level 2 (3-4 marks) Clear statements. Link between technique and how it works, the gabions absorb the power of the waves reducing erosion, the fences trap sand helping to build up the beach, sea walls reflect the waves and their energy. [4] Q19. Soft engineering involves things such as beach nourishment where sand is added to the existing beach and so protects the coast behind from erosion by forming a barrier, dune regeneration where sand dunes are stabilised by planting marram grass and areas are fenced off from people to prevent erosion, and these like the beach nourishment protect the area behind. Marsh creation where low lying areas that are seen as being unimportant are allowed to flood to protect other more valuable areas. Level 1 (Basic) (1 2 marks) Describes soft engineering strategy(ies). Statements are simple and separate. Sand is added to the beach. This is beach nourishment. Some areas are allowed to flood and marshes are created. Level 2 (Clear) (3 4 marks) The description is followed by clear attempt to explain. Statements are developed and linked the strategy to the way the land is protected. Extra sand is added to the existing sand on the beach. This acts as additional protection and is a barrier between the sea and the land, protecting the coast. Sometimes, areas are allowed to flood and marshes are created. These areas then take the force of the sea and protect more valuable areas once they have been sacrificed. AO1 2 AO2 2 [4] Q20. The diagram shows a number of hard engineering strategies. Revetments that are built along the line of the cliff but in front of them. Groynes at right angles to the cliff as well as rock armour where huge boulders are placed at the base of the cliffs. Revetments ensure that waves break in front of or on these, protecting the bottom of the cliff; they often allow material to go through and build up behind, offering further protection. Rock armour works in a similar way but is usually directly at the base of the cliffs and this absorbs the power of the waves and so protects the coast behind. Groynes work in a different way as they are built at right angles to the coast and so try to keep beach materials in place and prevent longshore drift from occurring and so enabling the beach to protect the cliffs. Other hard engineering strategies can also be used such as sea walls which are specifically mentioned in the specification. Level 1 (Basic) (1 4 marks) Describes strategies shown in the diagram. Begins to explain at the top end. Simple separate statements. There are groynes shown. These are wood or rock fences built at right angles to the cliffs. Rock armour is found on a small part of this coast where rocks have been piled up against the cliff to try to stop erosion. Level 2 (Clear) (5 6 marks) Uses information in the diagram may refer to other hard engineering strategies.

41 There is a clear explanation. Develops and links statements. Rock armour and revetments are shown along the coast. These run along or just in front of the base of the cliff and are designed to take the force of the wave and so protect the cliff, meaning it is not undercut and so remains stable. Groynes are placed at right angles to the cliff at intervals along the beach. These catch the sand being carried in the waves and so the beach is not eroded. Instead, it stays to protect the bottom of the cliffs from the waves. AO1 2 AO2 2 AO3 2 [6] Q21. Level Marks Description 2 (Clear) 3 4 AO2 Demonstrates clear understanding of how coastal defence(s) work in defending the coast. AO3 Application is sound with clear interpretation of the strategies shown in the photograph. 1 (Basic) 1 2 AO2 Shows limited understanding of how the coastal defence(s) work. AO3 Application is limited with basic interpretation of the strategy(ies) shown in the photograph. 0 No relevant content. Indicative content (Curved) sea walls reflect the energy of the waves back to the sea. They protect the base of cliffs, land and buildings against erosion and can prevent coastal flooding in some areas. Rock armour consists of large boulders piled up on the beach. These absorb the energy of waves and may allow the build-up of a beach. No credit for simply identifying the type of sea defence or for describing other hard (or soft) engineering strategies. AO2 = 2 AO3 = 2 [4] Q22. The question is about protection, there is no specific need for detailed reference to erosion/flooding. This question is not about environmental management. Level 1 Basic (1 4 marks) Max 2 marks for a list of methods with no explanation, i.e. (Sea walls, groynes, gabions, rip rap etc). Some explanation for 3-4 marks.

42 In some areas concrete sea walls and gabions, which are wire baskets filled with rocks, are put in front of the cliffs to stop the waves hitting them. This can stop erosion. Level 2 Clear (5 6 marks) Clear description of methods and understanding about how they work. There are many types of coastal defences including sea walls, gabions, groynes and rip rap. Sea walls are built in front of cliffs and they stop the waves hitting the cliff. Some are curved and this throws the breaking waves back out to sea. Rip rap or large boulders are placed in front of cliffs or sea walls. They take the energy from the waves so it does not damage cliffs or break down the sea wall. Groynes trap sand to create a beach which protects the land. [6] Q23. Level Marks Description 3 (Detailed) 5 6 AO3 Demonstrates thorough application of knowledge and understanding to analyse geographical information, giving detailed explanation of formation of the features shown. AO3 Makes full analysis of the resource, using evidence to support response. 2 (Clear) 3 4 AO1 Demonstrates specific and accurate knowledge of processes and landforms in depositional coastal environments. AO2 Shows clear geographical understanding of the interrelationships between coastal environments and processes. 1 (Basic) 1 2 AO1 Demonstrates some knowledge of processes in depositional coastal environments. May be limited to an explanation of longshore drift and other processes only. Alternatively the account may be descriptive and be confined to landform appearance and structure. AO2 Shows limited geographical understanding of the interrelationships between coastal environments and processes. 0 No relevant content. Indicative content Responses should analyse the map, finding connections and providing a logical chain of reasoning. The question implies knowledge of the processes of transportation and deposition as well as landform(s) of deposition. Emphasis is on explanation, so processes

43 should be outlined as well as the sequence of formation. In the specification the relevant landforms are beaches, spits and bars, but credit other variations such as tombolos and barrier islands. The landforms are created by the process of longshore drift. Some eroded material is caught up within the waves and is carried by the sea along the coastline. Material is carried along the shore in a zigzag fashion by waves as they swash material up the beach at an angle and backwash material down the beach at a right angle. The angle of swash is determined by the prevailing wind. On the map the direction is from west to east as shown by the prevailing wind, and the shape and growth of the spit. Credit processes of transportation such as traction, saltation and suspension. Allow labelled diagrams as part of the explanation of processes and landforms. Spits are formed by longshore drift in areas of relatively shallow and sheltered water where there is a change in the direction of the coastline. Deposition occurs, resulting in the accumulation of sand and shingle. The material initially deposited is the largest material, dropped due to the reduction in energy. A bay bar may develop across the entrance to a bay and eventually join two headlands due to transport of sediment by longshore drift. Beaches are areas of sand, pebbles and shingle that are formed by deposition produced by wave processes and by longshore drift. Gently sloping beaches are formed by strong destructive waves that backwash more material away from the beach than they swash up the beach. Steeply sloping beaches are formed by constructive waves that swash more material up the beach than they backwash away, building up a steep beach gradient. AO1 = 2 AO2 = 2 AO3 = 2 [6] Q24. (i) (ii) Three different landforms should be identified cliff, wave cut platform, headland, bay, cove, stump (only small feature). Answer should refer to the existence of a line of weakness in a cliff face e.g. a joint, crack that is eroded by the sea to form a cave. Hydraulic action and abrasion are particularly responsible for making the cave bigger. Rock is relatively hard or it will simply fall. If there are two caves on either side of the headland, continued erosion will result in a hole being formed, joining the caves to form an arch. As further erosion takes place, the arch will eventually collapse, as it cannot be supported. The seaward end of the arch will form a sea stack an isolated piece or pieces of rock, separate from the headland. Level 1 (1-2 marks) Basic statements with limited sequence e.g. sea attacks the rock, hollow is formed, gets bigger and rock above falls. Level 2 (3-4 marks) Clear, more developed answer with clearer, more complete sequence and more appropriate terminology e.g. waves attack a headland and erode a crack in the rock. A cave is formed due to abrasion. This gets bigger and forms an arch which collapses leaving a sea stack. Level 3 (5-6 marks) Detailed, well developed answer with clear and complete sequence; appropriate terminology, clearly links sequence to landform 3

44 e.g. waves attack a crack in a headland. This is enlarged to form a cave by the pounding of the waves compressing air in the rock face and abrasion where material carried by the water is flung against the cliff. In this way, the cave is made bigger and, if there is one on either side of the headland, an arch will result when they join. Continued erosion will wear away the rock supporting the arch and this will collapse. This will leave an isolated piece or pieces of rock separated from the headland a sea stack. 6 [9] Q25. (i) Diagram should show land/coast, beach, sea and direction of prevailing wind. Particle should be shown with movement up the beach an angle and labelled swash; down the beach at right angles to the coast and labelled the backwash; and movement overall of the material along the beach labelled as direction or longshore drift. 1 for sketch and 2 x 1 for labels AO1 1 AO2 1 AO3 1 (ii) Deposition occurs when there is too little energy to transport material and so it is left behind. This occurs where the coast is sheltered and so waves are not very powerful; where constructive waves are present it can occur when too much material is being carried where there is a large supply of sediment being brought down by rivers; where there is high coastal erosion nearby; where groynes are placed on the beach. 3 1 or 1+(1+1) 3 AO1 3 [6] Q26. (a) (b) 3 1 for labelling any 3 valid landforms arrow must make contact with feature for mark. Landforms such as headland, cliff, cave, arch, wave-cut notch. 3 1 AO2 1 AO3 2 3 Waves erode the base of the cliff via hydraulic action and abrasion. A cave forms as a crack / weakness is exploited by the waves. On a narrow headland, continued erosion extends the caves backwards and once it breaks through the headland, an arch forms. Further erosion at the base widens the arch. Eventually the roof of the arch will not be able to be supported by the rock below. This collapses to leave a sea stack an isolated pillar of rock, now detached from the headland. Level 1 (Basic) (1 2 marks) Simple points. Order not correct jumps about.

45 Sequence may be incomplete. The sea erodes the bottom of the cliff. An arch forms. Eventually, this collapses to leave a sea stack. Level 2 (Clear) (3 4 marks) Complete, clear statements. Statements are developed and linked. Sequence and formation of a stack is complete and clear. Waves erode a crack in a headland. This leads to a cave forming due to hydraulic power and abrasion. Over time, the cave gets bigger and finally breaks through the headland to form an arch. Weathering of the roof and erosion at the base widen the arch. A point comes when the roof cannot be supported and this collapses. This results in the formation of a sea stack an isolated pillar of rock once attached to the headland. AO1 3 AO2 1 4 [7] Q27. (i) 4 1 Arch Cave Stack Wave cut platform 4 (ii) Level 1 Basic (1 3 marks) Basic understanding of process (names of processes with no real explanation) and incomplete sequence. The sea hits the cliff and it is eroded forming caves and arches. Eventually the arch gets bigger and collapses leaving a stack. Level 2 Clear (4 5 marks) Some clear link between processes and features and an understanding of the sequence of erosion. The force of waves hitting the bottom of the cliff causes cracks and caves to develop. The waves carry sand and this speeds up erosion when it hits the cliff. Where land sticks out into the sea, the caves on each side break through to form an arch. With continued erosion, the arch collapses, leaving a stack. 5 [9] Q28. (i) 1 mark breaking down/rotting/decay of rock by the action of the weather 2 nd mark some development beyond basic definition. Might include: named example / rotting of rocks some explanation of an example mention of chemical processes In situ acid rain not just rain

46 2 (ii) 1 mark wearing away/removal of rocks by water or wind 2 nd mark name of specific process explanation of specific process 2 (iii) Level 1 Basic (1 2 marks) Basic description of how erosion is changing the landscape. The sea bashes against the cliff and it begins to fall apart. Caves are formed where the sea hits the cliff and these get bigger and bigger, eventually the cliff collapses. Level 2 Clear (3 4 marks) Clear understanding of processes or sequence of erosion or incomplete understanding of both. The sea hits the bottom of the cliff and this erosion wears the cliff away, forming caves. Continued erosion of caves through the cliff forms an arch which eventually collapses, leaving smaller stacks. Level 3 Detailed (5 6 marks) Detailed understanding of processes and sequence of erosion. Use of technical language. The base of the headland is attacked by waves. The force of the waves, hydraulic action, and material being thrown against the cliff, corrasion, creates caves at the base of the cliff. As the caves become larger and break through the headland an arch is formed. Continued weathering and erosion of the arch leads to roof collapse, leaving stacks. Eventually the whole headland will be eroded away leaving the base of the original feature a wave cut platform. 6 [10] Q29. The diagram shows a number of hard engineering strategies. Revetments that are built along the line of the cliff but in front of them, and groynes at right angles to the cliff as well as rock armour where huge boulders are placed at the base of cliffs. Other hard engineering strategies can also be used such as sea walls which are specifically mentioned in the specification and the candidate's own case study can be used to answer the question. There should be a focus on the costs of hard engineering strategies, such as initial high cost e.g. 6 million for a km of sea wall, the fact that it is not a one-off cost as maintenance is needed as these and boulders are pounded by waves, that they can be seen as spoiling the appearance of the area and, in the case of groynes especially, interfering with natural processes and having unwanted effects further along the coast. Benefits should also be noted the success rate in achieving protection, the presence of promenade on the sea wall in tourist resorts, the attraction of tourists by keeping the beach in place, security in the knowledge that people s homes are safe and plans can be made in the long term. Candidates can use the diagram as a trigger for ideas which they develop or to include either strategies or case study material any approach is valid. Level 1 (Basic) (1 4 marks) Describes hard engineering strategies. Simple statements may be in random order.

47 Hard engineering involves building revetments the fences shown in the diagram along the bottom of the cliff and also those at right angles groynes. This means that the foot of the cliff is protected and the beach kept in place. Rock armour is also present near the lifeboat station which is where boulders are piled at the foot of the cliff. Level 2 (Clear) (5 6 marks) Begins to discuss either costs and / or benefits. Statements are developed and linked. Specific reference to the diagram and / or own knowledge. The groynes placed at right angles to the cliff at Happisburg are expensive and can cost 10,000 each. A number are needed along the beach so a lot of money is needed. They can also interfere with the movement of the sand along the beach. While the area where they are found will keep its beach, areas further along the coast will have no material and so their beach will disappear. This may threaten people s homes. Level 3 (Detailed) (7 8 marks) Discusses both costs and benefits. Diagram is purposefully used for ideas and these are targeted to question. Statements are detailed and linked. Specific reference to the diagram and own knowledge. The rock armour placed at the foot of the cliff is expensive up to 4000 per metre but this is nowhere near as expensive as a sea wall which can cost 6 million for just a km. This is a huge amount of money for something which will protect the coast effectively, but which will also need maintenance to make sure that it is in a fit state to protect the area behind it. These measures give people peace of mind, knowing that their homes will not be threatened. Groynes try to keep sand in place and stop longshore drift. This is a benefit for people living where the groynes are found as if it is a seaside resort, it means tourists will keep coming and people s incomes will be safe. However, it is a different story for people along the coast as the starving of the sand to these sites may increase erosion and cause houses and businesses to be lost. It is a question of weighing up pluses and minuses and accepting that there are likely to be some winners and some losers with these measures. AO1 3 AO2 3 AO3 2 [8] Q30. Near the beach, the vegetation is dominated by grasses there is more than one species as seen by the different colours / leaves. One grows taller than the other. Vegetation cover is incomplete there is much sand exposed. Further from the sea, the cover is complete and there is more variety. Grass is present in smaller quantities and there are more small shrubs present. Level marking Level 1 (basic) 1 2 marks Simple, separate listed points. Some reference to the photograph(s). There is a lot of sand present near the sea. Grasses are growing. Inland, there are shrubs. Level 2 (Clear) 3 4 marks Points are developed and linked. Pictures / changes can be visualised. Specific reference to the photograph(s). There are large gaps in the vegetation cover near the sea. Further inland, the cover is complete. The main vegetation is grass near the sea. There seem to be two types

48 as the leaves are different colour and they are different heights. Further inland, there is much less grass and taller shrubs present. AO1 1 AO2 1 AO3 2 [4] Q31. (i) Simple copy (word for word with nothing else) of annotations on the figure NO MARKS Level 1 Basic (1 4 marks) Basic ideas which are largely copied from the resource. Some awareness of how managed retreat works for 4 th mark. Some of the land is allowed to flood and this means the water can spread out. Marshes can develop and trees will grow. Also an earth bank has been built which stops water moving inland. Level 2 Clear (5 6 marks) Clearer idea of how managed retreat uses the natural environment to protect inland areas. Managed retreat means that some land can be flooded but this allows that land to absorb most of the water from storms and when higher land is reached it provides a natural barrier. It means that large defences are not needed and the land itself is used to protect inland areas. Level 3 Detailed (7 8 marks) Detailed appreciation of how managed retreat can act as a natural defence. Managed retreat allows floodwater to encroach on the land up to where the land is naturally higher. This gives more space for wave energy to be absorbed. As salt marsh and vegetation develops it provides a natural protection against storms. An earth bank is also built. This is a natural looking feature that provides protection in the event of a severe storm. 6 (ii) 2 x 1 mark or 1 x 2 marks (developed point) 1 mark more wildlife/more trees/vegetation/nature reserve/less damage to environment/specific environments (saltmarsh) no visual pollution 2 marks different environments can develop which are good for wildlife different environments develop which are good for birdwatchers' does not damage the environment like hard engineering schemes 2 [8]
