3 Mechanical Weathering Processes that Break Down Rocks
From the initial stress of the rock to the gradual crack, this mechanical weathering varies based on the composition of rocks. For example, igneous rocks like granite are stronger and more resistant to mechanical weathering than sedimentary rocks. Basalt weathers quickly with water. And one of the fastest-weathering rocks is limestone.
