Module 5 Exogenic process i

1. Module 5 E xogenic Processes Earth Surface composed of WATER and LANDMASSES. PROCESSES: WEATHERING, EROSION, DEPOSITION

2. WEATHERING -Process of disintegration and decomposition of rocks. -important process in the formation of rocks. 2 Types of WEATHERING Mechanical or Physical Weathering Chemical Weathering

3. Mechanical or Physical Weathering -breakdown of rocks into pieces without any change in composition. 2 . Chemical Weathering - There are changes in composition due to chemical reactions.

4. Soil -a mixture of grains, organic matter, water and gas. EROSION -the separation of weathered rocks due to different agents like: water ,wind, glacier. Plant ,animals, and humans play an important role in the erosional process.

5. Mass Wasting -the movement of sediments downslope under the influence of gravity. Example : fall, slide, and flow. Deposition -the process in which the weathered materials carried out by erosion settle down in a particular location.
