Weathering

the process by which rock or soil is broken down

2

Erosion

the process by which rock or soil is broken down

3

Deposition

the process by which eroded rock, soil, or other earth materials are laid down in new places

4

Meander

broad curves in mature and old rivers

5

Oxbow Lake

a meander cut off from a river that forms its own lake

6

Delta

a buildup up sediment deposition formed where a river flows into a larger body of water

7

18

Sand dunes

large amounts of sand deposited from wind

19

Mass Wasting

general term for erosion of large amounts of loose soil, rocks, and other materials due to gravity

20
