What determines Rate of Weathering? - important factors that determine the rate at which weathering:

Sun or forest fire heats outside of rock, rock then starts to flake

The chemical and physical processes that breakdown rock at Earth's surface

water sinks through air pockets in soil :result is weak acid : Carbonic acid easily weathers

some rock weathers easily because it is
