Across
- 3. Water located within the rounds below the earths surface
- 5. Movement of matter due to differences in density
- 8. Outermost layer of the earth made of the crust and top of the mantle.
- 9. crust Part of the lithosphere above that is thicker and less dense
- 10. a boundary When two tectonic plates collide into each other
- 12. Layers of deposited sediment that can form a flat area
- 15. Natural process by which atmospheric and environmental agents such as rain, ice and temperature changes, and decomposes rocks
- 18. Tiny grains of broken down rocks
- 19. tectonics The theory that explains how tectonic plates move
Down
- 1. Movement of the tectonic plates caused by convection in the asthenosphere
- 2. A fan shaped pattern where sediments are deposited
- 3. Standard method used to divide long natural history in manageable parts
- 4. fan A fan shaped deposit that forms on land
- 6. Block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
- 7. part of the lithosphere that is thinner and is underwater, but less dense
- 11. Where old rock is destroyed as new rock rises and cools becoming less dense
- 13. a boundary When two tectonic plates slide pass each other horizontally
- 14. a boundary When two tectonic plates move away from each other
- 16. Movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault
- 17. The process which water, ice, wind, or ground move soil and sediment
