Gravity and water are two causes of physical weathering.
There are many causes of weathering. Some of the main causes of weathering are:Thermal stressFrost weatheringOcean wavesPressure releaseSalt-crystal growthBiological effects
physical weathering
WEATHERING and EROSION
Exfoliation is primarily caused by physical weathering processes such as thermal expansion and contraction, where daily and seasonal temperature changes cause rocks to expand and contract, leading to the outer layers of rock peeling off in sheets. This process is especially common in areas with extreme temperature fluctuations like deserts.

Erosion and weathering are the key forces.
