The document discusses exogenic processes that shape the Earth's surface, including weathering, erosion, and deposition. It defines weathering as the breakdown of rocks, dividing it into mechanical and chemical types, and explains erosion as the removal of weathered materials by agents such as water and wind. Additionally, it covers mass wasting, which is the movement of sediments due to gravity.

1. Module 5
Exogenic 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
1. Mechanical or Physical Weathering
2. Chemical Weathering

3. 1. 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.
