• carbonation

• rust

• oxidation

• abrasion

What determines how quickly a rock weathers?

• Earthquakes in the area

• Animals digging in the dirt

• Chemicals breaking down rock

How does deforestation contribute to erosion and depostion

• No trees allows the wind to blow harder therefore it erodes away more soil.

• Without trees the water in rivers moves faster, allowing more soil to be eroded away.

• Tree roots keep soil in place therefore wind and water cannot erode the Earth as quickly.

• Tree roots weigh mountains down and therefore wind and water cannot erode the Earth as quickly.
