Explain the process involved in gradation, degradation & aggradation.
Answers
Answer:
Explanation:
gradation is the process of levelling the land by means of moving agents like rivers, winds, sea and waves. The highlands are made low by erosion or wearing away and the lowlands are raised by adding the eroded materail by the process of deposition.In geology, degradation refers to the lowering of a fluvial surface, such as a stream bed or floodplain, through erosional processes. Degradation is the opposite of aggradation.
Answer:
geology, degradation refers to the lowering of a fluvial surface, such as a stream bed or floodplain, through erosional processes. Aggradation (or alluviation) is the term used in geology for the increase in land elevation, typically in a river system, due to the deposition of sediment. Aggradation occurs in areas in which the supply of sediment is greater than the amount of material that the system is able to transport.
