This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

Which of the following actions causes the deposition of sand at a delta?

• river water slowing as it enters the ocean

• salt water & fresh water mixing together

• ocean waves transporting sand toward land

• ocean water slowing as it reaches the coast

How do plants weather rocks?

• During photosynthesis
• When roots grow into cracks of rocks and expand the rock breaks.
• When the plant moves water from the roots to the leaves, the rock breaks.
• Plants don't weather rocks.

How does vegetation in the soil affect the rate of erosion?

• It doesn't affect erosion.

• It decreases erosion.

• It increases erosion.
