2 Restless Earth 1. Structure of the earth Using the textbook complete the following statements: - Continental crust is than oceanic crust. - Oceanic crust is more than continental crust - Oceanic crust is under and continental crust is under - The is solid metal - The mantle is more at the top. oceans core thicker dense land solid

3 Restless Earth 2. Plate boundaries/margins Using the textbook fill in the table below with details about each margin type (destructive has been done for you) Margin type Description Features Hazard Destructive Oceanic plate subducts under continental breaking bits off which allows magma to rise to the surface Trench Fold mountains Volcanoes Earthquakes Constructive Conservative Collision

4 Restless Earth 3. Earthquakes and volcanoes Using your book/resource booklet and the text book make a list of primary and secondary impacts of the following tectonic hazards: Kashmir earthquake Mt St Helens eruption Primary effects Secondary effects

5 Restless Earth 4. Managing tectonic hazards Type an answer to the following question below: How can people reduce the impact of earthquakes (4 marks) One way people can....

6 Climate and change 1. Natural causes of climate change Complete the following sentences (the last one has been done for you): Orbital changes cause climate change by... Solar output changes earth s climate... Volcanic eruptions cause ash and dust to block the sun s rays which cools the planet causing climate change.

7 Climate and change 2. Human causes of climate change Add the correct greenhouse gas to the following statements By burning fossil fuels such as oil for energy and transport this greenhouse gas is produced. Humans are breeding more cows in order to feed the increasing global population. These cows release this greenhouse gas when they pass wind. Methane Carbon Dioxide (CO2)

8 Climate and change 3. Climate change impacts Make a list of benefits and negatives of future climate changes for the UK (which are which) Increase in tourism due to warmer summers New crops such as wine More storms leading to flooding Decrease in winter sports in Scotland due to melting snow.

9 Battle for the biosphere 1. Distribution of biomes Identify if the following statements are true or false: Delete all false statements Tropical rainforests are found near the equator Tundra are frozen grassland near the arctic circle Deserts are hot and wet Most tropical rainforests are in Europe It is more likely to rain near the coast than inland

10 Battle for the biosphere 2. Goods and services from the rainforest Identify which of the following are goods and which are services Raw materials (wood, paper etc...) Medicines Oxygen Flood defence Food (fruit etc...) Eco-tourism

11 Battle for the biosphere 3. Destruction of the rainforest Complete the definition of deforestation: Deforestation is... List 3 reasons why deforestation is occurring:

12 Battle for the biosphere 4. Protecting the rainforest Using the textbook describe the following global strategies for protecting the biosphere: 1. National parks 2. CITES 3. Rainforest conservation

13 Water world 1. Hydrological cycle Answer the following two questions: 1. What are the two largest water stores? 2. What is the fastest route of rain hitting the ground reaching the oceans again (groundwater flow, through flow or overland flow)?

14 Water world 2. Human interference with water Use the textbook and add any other human activities that affect water quality and supply Quality Human waste leads to diseases like cholera Quantity/supply Over abstraction when water is taken faster than it is replaced it runs out

15 Water world 3. Large scale water management Using your exercise book/resource booklet list 3 positives of the Colorado River management programme and three negatives of the Three Gorges Dam.

16 Water world 4. Small scale water managemet Using the textbook answer the following question: Why can intermediate technologies be beneficial for the developing world?

17 Coastal change 1. Coastal erosion Match the following erosion processes to their meaning: Hydraulic action When particles are picked up and thrown against the coast they break bits off. Abraision Attrition Erosion caused by water smashing against the coast causing cracks to appear When rocks and other sediment smash into each other in the water they get smaller

18 Coastal Change 2. Deposition What is the difference between destructive and constructive waves?

19 Coastal change 3. Coastal management Give two hard and two soft engineering methods and give one advantage and one disadvantage for both (possible methods below) Sea wall Groynes Rip rap Beach replenishment Managed retreat Cliff Regrading
