Vocabulary

Weathering Mechanical or chemical surface processes that break rock into smaller pieces.

Mechanical Weathering Physical processes that break rock apart without changing its chemical makeup; can be caused by ice wedging, animals, and plant roots.

Chemical Weathering Occurs when chemical reactions dissolve the minerals in rocks or change them into different minerals.

Climate Average weather pattern in an area over a long period of time; can be classified by temperature, humidity, precipitation, and vegetation.
