1 1st 9 Weeks District Common Assessment Review Wednesday, Oct. 12 Test Date! What were the 3 pieces of evidence Alfred Wegener used to solidify his theory? 1. fossil evidence 2. landforms match up 3. coastlines fit together like puzzle pieces Wegener s Theory of Continental Drift was modified with the help of technology. The theory that we now accept is called the Theory of Plate Tectonics. Why could we find fossils from the same animal on two different continents separated by a large body of water? The contintents could have once been all together as a supercontinent called Pangaea. Name a landform that would be made at a convergent collision plate boundary. Tall mountain ranges In what direction are plates moving at a convergent collision boundary? They are moving towards each other. What is the name of the plate boundary where the plates move towards each other and up, and what landform is created at that boundary? Convergent/collision plate boundary. Tall mountains What is the name of the plate boundary where the plate move towards each other, but one is pushed underneath the other, and what landforms are created at that boundary? Convergent/subduction. Volcanoes, deep ocean trenches, island and volcanic arcs

2 What is the name of the plate boundary where the plate move away from each other, and what landforms are created at that boundary? Divergent plate boundary. Sea floor spreading, rift valleys, mid ocean ridges What is the name of the plate boundary where the plates slide past one another in opposite directions, and what landform is created at that boundary? Transform plate boundary. Faults and fault lines. Earthquakes occur along these faults. How did the Himalayan Mountain Range form? _ 2 convergent plates collided and pushed the mountains up. This is a constructive force. How did the Andes Mountains form? _ 1 oceanic plate subducted under a continental plate. This is a convergent/subduction boundary. How did the San Andreas Fault form? _ 2 plates slid past each other creating a fault. This is a transform boundary and it is also a destructive force.

3 How do you find change in elevation on a topographic map? _ Find the index contour lines on the map (line with numbers on them). Subtract the numbers to get the difference between the index lines. Count the number of spaces between the index lines. Last, divide the difference by the number of spaces. If you were a hiker and you hiked from point A to point B on the map, what would your change in elevation be? Please enter your answer on the grid. 500 ft Would you be hiking uphill, downhill, or both? Downhill What direction would you be hiking? Northeast

4 A section of a topographic map is shown below. What is the change in elevation, to the nearest 10 meters, between points X and Y? =360 m What are the 4 symbiotic relationships we learned? 1. mutualism 2. commensalism 3._ parasitism 4._ predator vs. prey Describe the interactions between organisms for each symbiotic relationship. (+,+, +,, etc) 1. mutalism both benefit (+,+) (+, ) (prey) 2. commensalism 1 benefits and the other is not affected (+,0) 3. parasitism 1 is benefitted (parasite) and the other is harmed (host) 4. predator vs. prey 1 is a hunter (predator) that hunts down its food

5 P. aurelia and P. caudatum are two species of organisms. The graphs above show how they reproduce over time. Graph (a) and graph (b) show how they reproduce when separate from each other. Graph (c) shows what happens when they are together. What do the graphs tell us about the 2 species when together? The number of P. aurelia are not affected by P. caudatum. However, the population of P. caudatum decreases when P. aurelia is present. Which symbiotic relationship includes an organism hunting down another organism for food? predator vs. prey What do we call the organism that hunts? predator What do we call the organism that is hunted? prey

6 What is competition? Competition is the demand for resources in short supply in a community. What 4 things do all organisms compete for? 1) food 2) water 3) shelter 4) space or territory Using the picture above, where would barnacles compete the most for space? during high tide where the two barnacle species contact each other If conditions in an ecosystem become less harsh, what are some results that can occur to the organisms that live in that ecosystem. food would be more plentiful, so animals could grow larger, due to more nutrients. What are some adaptations that organisms have gained from changes in their ecosystem?_ Different shaped beaks, the shapes of hooves, the ability to survive different climates

7 Name the predator/prey relationships in this food web. _ bobcat/squirrel, bobcat/ rabbit, bobcat/mouse, mountain lion/rabbit, mountain lion/deer, mountain lion/snake, mouse/grasshopper, snake/mouse, hawk/snake, hawk/mouse Name the producer/consumer relationships in this food web. _ acorns/squirrel, acorns/rabbit, berries/rabbit, berries/deer, grass/deer, grass/mouse, grass/grasshopper What often happens when two species operate in the same niche with limited resources? A. They will share resources without affecting either population. B. They will contribute to an increase in resources over time. C. Both populations will grow without limit. D. They will compete for available resources, causing a decline in one population and in the shared resource.

8 Name 2 producer consumer relationships from the food web: _ carrots/rabbits and grains/mice Name 2 predator prey relationships from the food web: foxes/rabbits and owls/grasshoppers If fungus and bacteria were added to this food web, would they be producers, consumers, or decomposers? decomposers What animals are competing for the grains as a food source? mice, grasshoppers, and birds In the image, which location is most affected by erosion from waves? Why?_ B because wind pushes the waves against the shore causing erosion. Point A is protected from waves.

9 Texas has hundreds of miles of coastline that the state must maintain. There are 2 problems the state faces: 1. Beaches often get washed away from the currents in the Gulf of Mexico 2. Shipping channels get too shallow for ships from sand that settles into the deeper lanes. How can both problems be solved at the same time? _ Humans could take the sand that settles in the shipping channels (dredge) and put it on the beaches to replace the washed away sand. Water run off containing fertilizers from farms and rural areas often flows into the lakes and ponds nearby. What might this do to the plant life that grows in and around the lakes and ponds? The fertilizer from the run off would make plants around the lakes and ponds grow abundantly and therefore kill off plants in the lakes and ponds by taking away nutrients. When there is a lot of flooding, the water in rivers, streams, lakes, and ponds gets very muddy. Why does this kill the plants that live in the water? _ Mud that is deposited reduces the amount of light that can reach plants. If there is no light then photosynthesis cannot take place. This would therefore reduce the amount of reproduction that could take place and kill off plants.
