Physical weathering, also called mechanical weathering or disaggregation, is the class of processes that causes the disintegration of rocks without chemical change. Physical weathering involves the breakdown of rocks … See more

Most rock forms at elevated temperature and pressure, and the minerals making up the rock are often chemically unstable in the relatively cool, wet, and oxidizing conditions typical of the Earth's surface. Chemical weathering takes place when water, oxygen, … See more

Buildings made of any stone, brick or concrete are susceptible to the same weathering agents as any exposed rock surface. Also See more

Wood can be physically and chemically weathered by hydrolysis and other processes relevant to minerals and is highly susceptible to ultraviolet radiation from sunlight. This induces photochemical reactions that degrade its surface. These also significantly … See more

Weathering of basaltic oceanic crust differs in important respects from weathering in the atmosphere. Weathering is relatively slow, with basalt becoming less dense, at a rate of about 15% per 100 million years. The basalt becomes hydrated, and is … See more

Granitic rock, the most abundant crystalline rock exposed at the Earth's surface, begins weathering with the destruction of hornblende. Biotite then weathers to See more
