Question

Which type of weathering is most commonly caused by animals?
Organic
Mechanical

Answer 1

The type of weathering most commonly caused by animals is **Mechanical weathering**. This occurs when animals, such as burrowing mammals, dig into the soil, which can break up rocks and soil particles. Their movements can physically disturb and fracture the material without changing its chemical composition. In contrast, organic weathering typically involves chemical processes influenced by biological activity, such as the decay of plant matter.
