False

Explanation:  

The breaking down of rocks and other materials on the Earth's surface is called as weathering.

When rocks are physically broken into smaller pieces it is called as mechanical weathering and when chemicals are used for breaking rocks into smaller pieces, it is called as chemical weathering.

Plants can cause both mechanical and chemical weathering. Mechanical weathering occurs when roots grow and cause the rock to break and  Chemical weathering occurs when roots release chemicals such as acids which then break down the rocks.
