Section 2A (Science 6)

A chemical change in which a substance combines with oxygen, as when iron oxidizes, forming rust.

• Abrasion

• Weathering

• Exfoliation

Match

• frost wedging

• A process which removes overlying layers (they peel like layers of an onion).

• frost heaving

• The lifting of rock or soil by the expansion of freezing water.

• exfoliation

• The grinding away of rock by other rock particles carried in water, ice, or wind (such as river rock)

• abrasion

• The splitting of rock when ice freezes /unfreezes repeatedly
