Types of Weathering Processes
- 1. Weathering
- 2. Kinds of Weathering Mechanical weathering Chemical weathering Biological weathering
- 3. Mechanical Weathering Mechanical weathering takes place when rocks are broken down without any change in the chemical nature of the rocks. The rocks are essentially torn apart by physical force, rather than by chemical breakdown.
- 4. The most common type of mechanical weathering is the constant freezing, and thawing of water.
- 5. Temperature changes also effect mechanical weathering. As temperatures heat up, the rocks themselves expand somewhat. As the temperatures cool down, rocks contract slightly. The effect can be the weakening of the rock itself.
- 7. Chemical reactions break down the bonds holding the rocks together, causing them to fall apart, forming smaller and smaller pieces. Chemical weathering is much more common in locations where there is a lot of water. This is because water is important to many of the chemical reactions that can take place.
- 11. hydrolysis
- 13. Effect of acid rain on statues.
- 14. Acid rain is caused by pollution.
- 15. Biological Weathring The word ‘bio’ means life. Thus biological weathering is any type of weathering that is caused by living organisms. Most often the culprit of biological weathering are plant roots. These roots can extend downward, deep into rock cracks in search of water, and nutrients. In the process they act as a wedge, widening and extending the cracks.
- 19. Other causes of biotic weathering are digging animals, microscopic plants and animals, algae and fungi.
