Physical Weathering includes:

• freezing and thawing

• plant growth

• grinding rock on rock

• acid rain

Process when water expands when it freezes, slowly expanding rocks until pieces break off

• freeze-thaw (ice wedging)

• chemical weathering

• combustion

• acidification

– rock is physically broken down into smaller pieces by physical processes grinding away of rock by rock particles carried by water, ice, wind, or gravity
