Weathering
Physical weathering
Physical weathering is when the weather makes the rocks crack because it changes from hot to called very suddenly
Biological Weathering
Biological weathering is where animals and plants weather rocks, for example, tree roots can grow into fractures in a rock and pull the rock apart
Chemical weathering
Rain falls down a rock and the minerals in the water react with the rock and becomes very smooth . If it has been affected by chemical weathering it will have lines down it
The breakdown of rocks by elements of the weather
e.g. wind, rain, temperature
