Exogenic Process: Weathering

The following are the agents of erosion EXCEPT:

• Gravity

• Ice

• Soil

• Wind

How does freezing water cause the weathering of rocks?

• causes rocks to fall in landslides

• expands cracks and breaks rocks

• keeps the rocks in place

• makes the rocks last longer

Erosion is transporting sediments from one place to another as well as weathering.

• True

• False

Caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.

• Chemical Weathering

• Mechanical Weathering

• Biotic Weathering

• Mass Wasting

Wind blown sand hitting a rock and slowly wearing it away is an example of

• Chemical erosion

• Mechanical erosion
