How do trees cause weathering of rocks?

Answer 1

When water freezes and becomes into ice, it expands. Imagine this inside the crack of a rock. Evidently the crack will only enlarge too. After freezing and thawing so many times bits of the rock break off.

Answer 2

Plants can cause both mechanical and chemical weathering.

Mechanical weathering occurs when roots grow and cause the rock to break (just like the roots that crack the sidewalk).

Chemical weathering occurs when roots release chemicals, like acid, which then break down the rocks.

Answer 4

Growing plants can cause both physical and chemical biological weathering. An example of physical (mechanical) biological weathering would be the growth of plant roots in rock crevices which pry the rock apart. Chemical biological weathering would be the production of acids by certain plants which cause a chemical change in a rock's surface chemistry.

Answer 5

Plant and roots cause weathering when the roots spread inside the rock causing it to push apart. The growth loosens and breaks ok pieces of the rock or mountain. - raegand

Answer 6

Their roots grow deep into cracks in rock where water collects. As they grow, roots become thicker and longer, slowly exerting pressure and wedging rock apart.

Answer 7

Trees weather rocks by their roots growing in small crevices, the root grows and sometimes it is strong enough to split the rock. this is also called Root Wedging.

Answer 8

Plants can break rock to pieces from roots growing in cracks of the rock. Plants can also help preserve landforms by preventing erosion by wind or water.
