Physical Weathering

Explanation:

As per the given conditions in the question, the primary effect is mechanical action which is also known as a physical weathering.

In the given statement, the root of tree would grow in the crack and try to develop a strong network to get nutrients necessary for tha tree growth. Thus, the root would exert a pressure in the crack to make more space for its growth and development (root network). This is primarily a mechanical action and an example of physical weathering.
