Root wedging occurs when roots grow into cracks in rocks, causing them to expand and break apart. This process is a type of weathering because it alters the materials it affects.

What is the initial step in the process of root wedging?

• Roots change the color of rocks.

• Roots dissolve the rocks.

• Roots grow in open spaces.

• Roots penetrate cracks in rocks.

How do roots contribute to the wedging apart of rocks?

• By attracting insects.

• By absorbing all the water.

• By expanding as they grow.

• By changing the rock's temperature.

What is the primary effect of root wedging on rocks?

• It wedges the rocks apart.

In what way is root wedging considered a form of weathering?

• It increases the size of the rocks.

• It breaks down and alters the materials it affects.

• It changes the temperature of the environment.

• It causes rocks to become smoother.

What happens to the materials affected by root wedging?
