Water Erosion. Erosion by water begins with a splash of rain. Some rainfall sinks into the ground. Some evaporates or is taken up by plants.

 Runoff  Streams  Rivers  Water picks up particles of clay, sand, and gravel as it moves along Earth’s surface  Small grooves form – called rills.

Presentation transcript:

Rivers are formed by erosion due to Running Water. River Features Rivers are formed by erosion due to Running Water.

Stream Stream - A channel through which water is continually flowing downhill.

Runoff runoff- water that flows over Earth’s surface.

Rills and Gullies Rill - tiny grooves in the soil created by runoff

Gully Gully - a large groove or channel in the soil that carries runoff after a rain.

Tributaries Tributary - a small stream that flows into a larger river

Flood Plain Flood Plain - a flat, wide area along a river.

Meanders Meander - a loop-like bend in the course of a river.

Oxbow Lake Oxbow Lake - a meander that has been cut off from the river.

Alluvial Fan Alluvial Fan - a wide, sloping deposit of sediment formed where a stream leaves a mountain range.

Delta Delta - a landform created when sediment is deposited where a river flows into an ocean or lake.
