• The soil is being removed because of the stream

WATER EROSION

• Water erosion is when earth's surface is being removed
• Water erosion is caused by streams or wind
• Ex: the edge of a river or ocean

WIND EROSION

• The edge of the little hill was blown away by wind

WIND EROSION

• Wind erosion is when wind destroys a large chunk of a rock

• Glacial erosion is when a glacier breaks down a rock
