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

• water carries soil from a garden to a sidewalk.

Which of the following is an example of tree roots slowing down weathering, erosion, and deposition?

• Tree roots break large rocks near a river.

• Tree roots hold soil in place near a river.

• Tree roots get worn away by river water.

• Tree roots grow very quickly near a river.

Hurricanes are powerful storms that can cause Earth’s surface to change. This tree’s roots pulled up soil when Hurricane Irma struck the Florida coast in 2017. What most likely caused the tree to pull up the soil?

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

• weathering

• erosion

• deposition

• sediments
