Physical Weathering

Rocks and minerals break down and change into smaller pieces of sediment

• mechanical weathering

• pressure

• oxidation

• erosion

chemical reaction with oxygen

• water, oxygen, carbon dioxide and acids

• chemical reaction with oxygen

• dig into rocks and break apart the material

• when carbon dioxide combines with the moisture in the atomosphere

burrowing animals

• plays another role in weathering

• removal and transport of weathered material from one location to another

• repeated thawing and freezing of water in the cracks of rocks

• dig into rocks and break apart the material

erosion

• rocks and minerals change their composition as a result of chemical reactions

• the process by which rocks on or near the Earth's surface break down and change

• removal and transport of weathered material from one location to another

• the outer layer is stripped away due to extreme temperature change

weathering

pressure

• repeated thawing and freezing of water in the cracks of rocks

• chemical reaction with oxygen

• dig into rocks and break apart the material

• another factor in weathering (exp: exfoliation)

acid precipitation - chemical weathering

• when carbon dioxide combines with the moisture in the atmosphere

• industrial burning of fossil fuels release sulfur dioxide while motor vehicle exhaust contains nitrogen oxides

• water, oxygen, carbon dioxide, acid rain

• chemical reaction with oxygen

frost wedging

• the process when rocks on or near Earth's surface break down and change

• repeated thawing and freezing of water in the cracks of rocks

• as roots grow , they expand and force the rocks apart

• the reaction of water with other minerals
