Animals are part of the biological weathering. Animals can scratch the rocks and dig out dirt. A seed can go inside a hole of a rock. The crack gives out moisture and shelter. After time the roots can grow and develops. The roots breaks up the rock. Then the tree grows. Mosses grow on and other little plants grow on bare rock surfaces. . Animals that tunnel underground, such as moles and prairie dogs, also work to break apart rock and soil. Other animals dig and trample rock above-ground, causing rock to slowly crumble. Biological weathering most common where there is a lot of rain and sunshine. Like for example there are quite common where it's like Brunei and places where is near the equator.
