Question

what is difference between erosion and deposition

Answer 1

hii...

#Erosion and deposition are continuous geological processes that are natural and result in relief features seen over the surface of the earth.

• If erosion is seen as a sequence of events, deposition takes place at last when the rock particles finally settle down on the surface of earth. So, erosion is the beginning of a process while deposition is the end of the same long process.

• Erosion is the movement of rock particles once they have been loosened by the action of natural agents of weather and others like roots of plants. Or, in other words, erosion is removal of loosened rock pieces from a higher elevation to a lowly point with the action of natural agents.

• When all particles falling and flowing under gravity is done with and all the sedimentation gets deposited and settles on the surface, we call it deposition. Now the particles that came a long way do not move anymore.

• Erosion can happen because of natural agents such as water, ice, and wind. However, when somehow these agents are disturbed and they cannot keep on dragging the particles, deposition takes place.

• Without erosion, deposition cannot take place..

Answer 2

While erosion is rock wearing, deposition is carrying of elements by wind.

• The differences between both are -

1. Erosion is when, natural forces cause rock fragments to be transported. Deposition is the process of transporting particles to a new site and settling them down.
2. Erosion is the first step in the transportation of rock particles, while deposition is the final step.
3. While erosion is caused due to water, people, wind etc, deposition arises from glaciers or reduced water speed.
4. Erosion leads to deforestation and soil degradation, whereas deposition leads to flow of chemicals from one place to other.
