Weathering is the natural process of

• moving soil for a different location

• loosening bits of rock from the soil

• breaking down rock

• materials settling out of the water

One example of erosion is when

Sand is made up of

• powdered clay

• weathered bits of rock.

• dried out soil.

• crushed animal bones

Hills called sand dunes form when

• the roots of plants hold sand in one place.

• water deposits in valleys.

• wind deposits sand in one place.

• burrowing animals dig holes.

Some plants, like moss, grow on rock and take minerals from it. It weakens the rock and causes it to break down. This is an example o

• erosion

• deposition

• sediments
