Weathering and Erosion 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 areas.

Agents of weathering are things that cause rocks to break down: Frost Temperature changes Plants Animals Rain
