1. Plate tectonics ch. 7

2. Ch. 7 Notes- Plate Tectonics
Theory that explains how large pieces of the Earth’s outermost layer move and change shape

3. What are examples of tectonic plates? (hint there are 10 total)

4. Answer: Cocos plate, North American plate, African plate, Indian plate, Eurasian plate, etc.

5. Convergent boundary
The boundary formed by the collision of two lithospheric plates

6. Divergent Boundary
The boundary between two tectonic plates that are moving away from each other

7. Transform boundary
The boundary between tectonic plates that are sliding past each other horizontally

8. What type of plate boundary do you think mountains are formed at? Why?

9. It’s not my fault!!!
Fault
A break in a body of rock along which one block slides relative to another

10. By looking at the picture below, what do you think occurs along a fault? Why?

11. Compression
Stress that occurs when forces act to squeeze an object

12. Which layer of the earth undergoes a lot of compression? Why?

13. Tension
Stress that occurs when forces act to stretch an object

14. Can you think of some examples of tension??

15. Folding
The bending of rock layers due to stress

16. Uplift
The rising of regions of the Earth’s crust to higher elevations

17. Subsidence
The sinking of regions of the Earth’s crust to lower elevations
