EROSION

WHAT IS EROSION?

• Erosion is the process that breaks things down, it moves bits of soil or rock from on place to another.
• Most erosion is preformed by water, wind or ice. ( usually in the form of a glacier.)

EROSION BY WATER

• Erosion by water changes the shape of coast lines.
• Waves constantly crash against shores, then they pound rocks into pebbles and reduce pebbles to sand.

WIND BY EROSION

• Wind is also an agent of erosion. It carries dust, sand, and volcanic ash from one place to another.
• Wind can sometimes blow sand into towering dunes.

EROSION BY ICE❄️💨

• The rocks carried by a glacier rub against the ground below, eroding both the ground and the rocks.
• Glaciers grind up rocks and scrape away the soil.

EROSION AND PEOPLE

• Erosion is a natural process, but human actually can make it happen more quickly.
• Trees and plants hold soil in place. When people cut down forests or plow up grasses for agriculture or development, the soil washes away or blows away more easily.
