Plate Tectonics and Topographic Maps Test Review Station #1 Match the cards. Tectonic Plate Boundaries. Answer the following questions in your journal under the heading of Station #1 – Tectonic Plate Boundaries. 1. What type of tectonic boundary created the Mid-Atlantic Ridge? Divergent 2. Describe what the tectonic plates are doing when volcanoes are formed. The oceanic plate to subducting under the continental plate forcing the magma upward forming volcanoes What kind of boundary is creating this crustal feature? convergent (subduction) 3. What 3 crustal features form when two plates collide? Trenches, Mountains, Subduction Zones, Volcanoes 4. Where will you find a rift valley? On land What type of boundary creates rift valleys? Divergent boundaries 5. Describe what the tectonic plates are doing at a transform boundary. Two side by side plates are moving in opposite directions 6. What crustal feature is formed at a transform boundary? Fault 7. List the crustal features that are formed at a divergent boundary. Midocean ridges, rift valleys Plate Tectonics and Topographic Maps Test Review Station #2 Define the following vocabulary words in your journal under the heading of Station #2 – Vocabulary. 1. Convergent boundary – two plates colliding into each other 2. Divergent boundary – two plates moving apart 3. 4. 5. Transform boundary – two plates moving side by side in opposite directions Subduction zone – one plate moves beneath the other Convection currents – these currents are the main cause of sea floor spreading, they occur in the Earth’s mantle when hot magma rises and cooler magma sinks 6. Weathering – breaking down of rock into smaller pieces - sediment 7. Erosion – moving of rock, soil, and sand 8. Deposition – the settling or layering of the eroded rock, soil and sand 9. Elevation – means height 10. Topography – The description and mapping of the physical features of the Earth’s surface Plate Tectonics and Topographic Maps Test Review Station #3 Complete tectonic plates puzzle. Answer the following questions in your journal under the heading of Station #3 – Tectonic Plate Puzzle. 1. What is sea floor spreading? Occurs where tectonic plates spread apart at Mid Ocean Ridges 2. Where will you find sea floor spreading and what type of tectonic plate boundary is occurring? In the Ocean; divergent boundary 3. What is being created at these ridges? New sea floor 4. Where will you find the youngest land? Closest to the mid-ocean ridges Plate Tectonics and Topographic Maps Test Review Station #4 Match the correct topographic map with the satellite image. Answer the following questions in your journal under the heading of Station #4 – Matching Topographic Maps 1. In detail, explain why you matched the topographic map you chose with the satellite image given. The canyon, indicated by the very close contour lines, can be observed spanning the center of the card. The smaller canyons branching off the main canyon have similar contour shapes. 2. What effects will erosion and weathering have on the landscape if the precipitation increased? The canyon would continue to broaden and deepen over long periods of time by weathering and erosion. Changes in precipitation amounts might increase or decrease the force of the river and therefore have an effect on the rate of weathering and erosion. 3. What do the blue lines in the topographic map represent? Water, rivers and streams Plate Tectonics and Topographic Maps Test Review Station #5 Read the topographic map provided. Answer the following questions in your journal under the heading of Station #5 – Reading Topographic Maps. 1. Define contour interval. The distance between two adjacent contour lines. 2. Define contour lines. Lines drawn on a map connecting points of equal elevation 3. What is the contour interval in the map? 50 4. When the contour lines are tightly spaced together on a topographic map, what does this tell you about the landscape being pictured? Steep in elevation 5. When the contour lines are widely spaced on a map, what does this tell you about the landscape being pictured? Flatter in elevation 6. How can you determine what the contour interval is if it is not already provided for you? Subtract the two adjacent contour lines ex) 100 - 50 gives you 50 Plate Tectonics and Topographic Maps Test Review Station #6 Put the Pangaea puzzle together. Answer the following questions in your journal under the heading of Station #6 – Pangaea Puzzle. 1. What is continental drift? Theory that the Earth’s continents move over time 2. Who proposed the theory of continental drift? Alfred Wegener 3. List 5 pieces of evidence that support continental drift. Continents fit together Similar fossils records Similar rocks and minerals Similar rock formations and striations Similar climatic conditions – Glaciations 4. What causes the tectonic plates to move? Convection currents in the mantle cause sea floor spreading making the tectonic plates move. 5. What layer of the Earth contains the tectonic plates? Lithosphere
