Chapter 3: Introduction
1.Weathering
2.Erosion
3.Denudation
4.Mechanical weathering
5.Chemical weathering
6.Transport
7.Deposition
8.Agents of weathering
The breaking down of rocks that lie
exposed to the weather.
The breaking down and movement
of rock pieces by water, ice and air.
Rocks are WORN DOWN
by the weather.
Mechanical weathering is the breaking down
of rocks into smaller pieces usually by frost,
the temperature changing or the movement of
plants or animals.
Rocks are chemically
changed or decomposed by
the rain
.
The movement of the
broken pieces of rock by
wind, ice or water.
The broken pieces of rock
are dropped in other

Agents of weathering are things
that cause rocks to break down:
