D
Trees do not cause rocks to weather.



Answer :

Growing tree roots physically break apart rock are the tree agents of mechanical weathering. So, the correct option is (A).

What is Mechanical Weathering?

Mechanical weathering is also called physical weathering in which a large rock breaks down into smaller pieces of rocks. When rocks decompose or break down without experiencing any change in their chemical composition, it is known as mechanical weathering.

There are 3 Mechanical Weathering Processes which break down rocks

  • Frost wedging.
  • Exfoliation.
  • Biological activity

The roots of a plant grow into a crack in a rock. When these roots grow, they open the crack. Burrowing animals can also cause weathering. The animal may break the rock to dig for food or make a hole to live in.

Thus, growing tree roots physically break apart rock are the tree agents of mechanical weathering. So, the correct option is (A).
