2. the process of rock breaking down into smaller pieces due to wind or moving water
5. the sudden pushing out of something, such as lava from a volcano
6. one of the very large sections of hard, solid rock that make up Earth’s outer layer
7. the rock type formed when sediment is pressed and glued together
8. the process by which rock material moves under Earth's outer layer and into the mantle due to plate motion
11. moving apart in different directions
13. the rock type formed when heat or pressure deep underground changes existing rock
15. a long, deep indentation in the ocean floor formed when two plates move together
16. the movement of sediment from one place to another, often caused by wind or flowing water
18. small pieces of rock
20. the slow pulling apart of land that is caused by plate movement
21. the layer of soft, solid rock underneath Earth’s plates

1. a sudden shaking of Earth’s surface
3. the process of sediment being glued together
4. evidence of life from the past, such as fossilized bones, footprints, or leaf prints
9. the process of sediment being buried and pressed together

12. moving toward the same place
14. the rock type formed when magma cools and becomes solid
17. the process by which all the rock formations of a region are pushed up due to plate motion
19. hot liquid rock below the surface of Earth
