Why does animals cause the weathering of rocks?

Animals contribute to the weathering of rocks through various activities, primarily through their movement and feeding behaviors. For instance, burrowing animals like moles and earthworms can disrupt soil and rock, exposing them to air and water, which accelerates chemical weathering. Additionally, animal waste can introduce acids that further break down minerals in rocks. Over time, these processes help to fragment and decompose rocks, contributing to soil formation.
