the process by which water, ice, wind, or gravity moves weathered rock

• erosion

• deposition

• runoff

• delta

small, solid pieces of material that come from rocks or organisms; earth materials deposited by erosion

• sediment

• gravity

• meander

• groundwater

the process in which sediment is laid down in new locations

• deposition

• mass movement

• runoff

• flood plain

a force that moves rocks and other materials downhill; the force that pulls objects toward each other

• gravity

• erosion

• stream

• alluvial fan

any one of several processes bu which gravity moves sediment downhill

• mass movement

• erosion

• gully

• rill

water that flows over the ground surface rather than soaking into the ground

• runoff

• sediment

• tributary

• karst topography

a tiny groove in soil made by flowing water

• rill

• gully

• flood plain

• stactite

a large channel in soil formed by erosion

• gully

• stream

• meander

• delta

a channel through which water is continually flowing downhill

• stream

• erosion

• mass movement

• stalagmite

a stream or smaller river that feeds into a main river
