• What causes deposition?

• What are the effects of erosion and deposition?

Erosion is a natural process of

• Erosion is a natural process of

• moving weathered rock and soil to

• another place. Erosion has a constant

• impact on Earth’s surface. Over millions

• of years, it wears down mountains by

• removing byproducts of weathering

• and depositing them elsewhere

Gravity constantly pulls material downward.

• Gravity constantly pulls material downward.

• Water such as rainwater,water from melting snow, rivers, streams, and waves carry rock and soil particles.

• Winds move small particles of dust through the air and larger particles of sand along the ground.

• Ice, in the form of glaciers, transport rock and soil particles as they move downhill.

Deposition is a natural process of

• Deposition is a natural process of

• laying down or depositing sediment in new

• locations.

• Deposition occurs when:

• wind slows down or stops blowing.

• water slows down or stops moving.

• glaciers melt.

The wind hits a boulder.

• The wind hits a boulder.

• It deposits the sediment.

• Wind removes sand and other sediment from the ground by the process of erosion.

• As the sediment piles up.

• Piles of sediment cause sand dunes to forms.
