Abrasion
Physical wearing down of rocks as they rub against each other
Alluvial Fan
Deposit of sediment formed where the velocity of a river slows as it flows out of mountains and onto dry land
Capillarity
Ability of water to rise in small openings
Chemical wearhering
Action resulting in changing chemical composition of a rock
Deposition
Release of sediments from an erosional system; also called sedimentation
Erosion
Carrying away/transporting of weathered rock materials by agents such as water/glacial ice/gravity
Evaporation
Liquid-gas
Flood Plain
Land between a stream and steep walls of a valley usually covered by stream during flood
Gradient

Hydraulic cycle
See water cycle
Infiltration
Water into regolith turns into groundwater
Mass movement
