Assessment criteria. Unit 9: A dynamic planet

1. Describe the direct methods used to study the geosphere.
2. Given a diagram of a relief, label the main features of it: mountain range, plain, coast, trench, abyssal plains, ridge.
3. Given a graph showing the variations in speed of P and S waves though a planet, describe, explaining your reasons, the layers of the planet: number, thickness and state.
4. Describe the internal structure of the geosphere according to the geochemical model:
   1. Layers: thickness, distance from the surface, sublayers and type of rocks.
   2. Discontinuities.
5. Describe the internal structure of the geosphere according to the geodynamic model:
   1. Layers: relation to the layers of the geochemical model and mechanical properties (fluid, plastic or rigid).
6. Explain Wegener’s theory and the evidences he based his theory on.
7. Explain the distribution of earthquakes and volcanoes in relation to the lithospheric plates.
8. Explain the distribution of the rocks that form the seabed according to their age.
9. Explain the distribution of paleomagnetic bands and its relation with the lithospheric plates.
10. Explain the use of laser and GPS to prove the movement of lithospheric plates.
11. State the proposals of the theory of plate tectonics.
12. Know the different types of plate boundaries and the effects that can occur in each of them: earthquakes, volcanos, new lithosphere, mountains, ridges, trenches, rifts, etc.
13. Explain what intraplate activity is and give an example of it.
