Ways in which animals cause weathering of rocks are;
- Burrowing animals lead to mechanical weathering by breaking up the rocks through digging.
- Hooved animals like cattle exert pressure on rocks as they walk on them leading to breaking and disintegration.
- Animals excrete chemical substances that may come into contact with the rocks and lead to chemical weathering.
- Decaying animal remains give off organic fluids that may react with the rocks and lead to chemical weathering.
