The weathering caused by living organisms is called biological weathering
It is the process by which rocks are broken into small fragments and fine particles due to the action of plants, animals and human beings.
The roots of the plants enter the points and ! cracks of the rocks in search of moisture.
As the roots grow bigger, they create tension in the rocks and start breaking them.
Animals such as mice, rabbits and rats dig I holes, anthills etc. and weaken the rock, which makes them loose and break into pieces.
