The diagram below shows the stump of a tree whose root grew into a small crack in bedrock and split the rock apart.

The action of the root splitting the bedrock is an example of
A)Physical Weathering
B)Chemical Weathering
C)Deposition
D)Erosion

As per the given conditions in the question, the primary effect is mechanical action which is also known as a physical weathering. During mechanical action, a rock is disintegrated into the smaller pieces. 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.
