What is physical weathering?

Physical weathering is the disintegration of rock by mechanical processes and therefore depends on the application of force. The applied forces could be: 

  • Gravitational forces such as overburden pressure, load and shearing stress; 
  • Expansion forces due to temperature changes, crystal growth or animal activity; 
  • Water pressures controlled by wetting and drying cycles.
