depends on the kind of rock the material it is made of.

mechanical weathering (by wind or water or perhaps tenacious plant roots or human activities)
Freeze-thaw weathering occurs when water seeps into cracks in rocks, freezes, expands, and creates pressure that can cause the rock to fracture or break apart. This process is common in regions with climates that experience freezing temperatures.
Sedimentary rock is formed by the processes of weathering, erosion, and deposition. These rocks are made up of sediments that have been compacted and cemented together over time.
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
The effect of weathering is to reduce the volume of the igneous rock.
Weathering may change the rock into many shapes.
By weathering either by physical or chemical weathering.
