conclusion on weathering and denudation
Answers
A negative correlation between sediment yield and weathering history, as measured by the chemical alteration (CIA) of the suspended sediment, is observed for many of the world's major rivers and other regions of denudation. The weathering history is a first-order control on the sediment yield of such areas, termed equilibrium denudation regions. For other areas, data scatter with either apparent increases or decreases of sediment yield for given CIA values. These areas are termed nonequilibrium denudation regions. Low sediment yields can be attributed to moderated erosion (either natural or human induced) and/or the incorporation of unweathered glacial debris. Accelerated erosion, resulting in high sediment yield, is primarily human-induced and results from cultivation and other land use. Each of these effects has a profound influence on global sediment discharge from the continents. Pre-human suspended sediment discharge from the continents is estimated to be or about 0.6 the present discharge.
Conclusion on weathering and denudation
Explanation:
- Weathering is the breakdown of the soil and rocks and the wood and the artificial material and through the earth atmosphere and the biological organism with the little or movement of the agent such as the water, ice, and the gravity and the wave and being transported and deposited in various locations.
- While the deduction involves the process of the wear and the tear of the rocks and earth surface features by the moving water and leading to ta reduction of the relief and elevation of the landforms such as the volcanoes ad the tectonic plates and exposing the crust to the exogenous processes of the weathering, erosion and the mass wasting.
