Explanation:

Weathering or weathering is a set of processes of a physical, chemical and biological nature that contributes to the formation of relief and climate in the world, since it interferes with the transformations of rocks and contributes to the formation of soil.

Mechanical weathering occurs through physical processes, with the fragmentation of rocks thus forming various types of sediment (eg sand). It is mainly influenced by temperature and pressure variation. Thus, the process of rock dilation favors its fragmentation. Despite being caused by physical processes, mechanical weathering has organic influences such as plant roots, prairie dogs, burrowing snakes.

it takes hundreds of years to become stable.

if you have another question lmk.
