Weathering & Erosion

1. an underwater or exposed ridge of sand, gravel, or shell material
3. the major agent of erosion that shapes our land surface
5. type of weathering when acid rain breaks down and changes the rock
6. this is the source of the majority of Earth's energy
7. an area of shoreline that is made up of material deposited by waves and currents
13. these are fertile, flat areas that are formed when a stream floods and a layer of sediment is deposited
17. the amount of energy through Earth's system forms an energy ____________
19. the process by which water, wind, ice and changes in temperature break down rock
20. the gases that surround Earth
22. the mostly solid, rocky part of the Earth
23. rock composed of minerals formed from solutions or sediments from older rock
24. this is made up of living things
26. a rapid movement of a large mass of mud
27. rock that is formed when magma or lava cools and hardens to become solid
29. the process by which sediment is moved from one place to another
31. a large mass of moving ice that forms by compacting snow by natural forces

2. the breaking down and wearing away of rock material by the mechanical action of other rock
4. the sudden and rapid movement of a large amount of material downslope
8. the part of the Earth that is liquid water
9. the process by which the outer layers of rock slowly peel away due to pressure changes
10. the water located within the rocks below
11. rock formed when pressure or temperature change existing rock
12. the process by which other chemicals combine with oxygen
14. this gas makes up the majority of the atmosphere
15. the process by which sediment comes to rest
16. mounds of wind-deposited sand
18. an increase in ________________ gases can increase Earth's temperature over time
21. the place where land and a body of water meet
25. ice _______ can cause rocks to physically break apart
26. this is known as molten rock
28. thick deposits of windblown, fine-grained sediment
30. the slow movement of material downslope
