Why do urban areas have more runoff than rural areas?

Back

Transpiration is the process by which water vapor is released from plants into the atmosphere.

Front

What is evaporation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface.

Front

What is physical weathering?

Back

Front

What is ice wedging?

Back

Ice wedging is a type of physical weathering that occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What factors affect stream velocity?

Back

Stream velocity is affected by stream discharge, slope, and shape.

Front

What is stream discharge?

Back

Stream discharge is the volume of water flowing through a river or stream at a given time.
