Chemical Weathering – e.g dissolution by acid rain. Physical Weathering – e.g. freeze thaw action. Biological Weathering – e.g lichen growth.
What types of weathering would act on a gravestone?
Chemical Weathering
Oxidation is caused by iron in the stone oxidizing or rusting when water and air are present. This causes stains to the gravestone and can often be seen as the orange/yellow/brown patina on sandstones due to their mineral content.
