EARTH SCIENCE

3. occurs when two plates moves away
5. is a force acting on a rock per unit area, Any rock can be strained. Strain can be elastic, brittle, or ductile
7. strata dip toward axial center
8. strata dip toward center in all direction
9. folds in adjacent layers with different wavelengths and shape
11. a break in earths crust where older rocks are pushes above younger rock
13. oldest strata in the center
15. a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other
18. occurs when the hanging wall moves down relative to the foot wall
19. angular fold with straight limbs and small hinges

1. a fracture or zone of fractures between two blocks of rock.
2. when the hanging wall moves up
4. strata dip away from axial center
6. force exerted by a cold, dense oceanic plate plunging into the mantle due to its own weight.
7. youngest strata in the center
10. occurs when two plates moves toward each other
12. is the result of gravitational forces acting on the young, raised oceanic lithosphere around mid-ocean ridges
14. bottom of the ocean
16. strata dip away from center in all direction
17. a fault along a plate boundary where the motion is predominantly horizontal.
