WEATHERING AND EROSION OF

EARTH'S SURFACE

Weathering

the breaking down of rocks into smaller pieces, mechanically or

chemically

Erosion

the movement of sediments to a new location because of

weathering

???????? (How is this concept supported by the law

of conservation of mass?)

Factors of Weathering And

Erosion

Water

Runoff is water flowingon Earth’s surface that causes erosion.

IceIn some parts of the world, ice

is an agent of erosion. Ice forms continental and valley

glaciers.

AirWind, which is moving air, blows small particles from Earth’s surface, which is called deflation. Pits in rocks or polishes surfaces smooth as sediments are blown

by strong winds, which is abrasion.
