Question

Difference between erosion and deposition

Answer 1

Erosion refers to the gradual transport of materials around the Earth's surface. Since erosion always travels in a down-slope direction, it can result in the wearing away of natural features. Erosion is one of the most important processes shaping the Earth's surface. Deposition is the final step in the erosional-depositional system. Rock particles that are picked up and transported by one of the eroding agents will ultimately be deposited somewhere else, and agents of erosion become agents of deposition. Final deposition of particles (sediments) usually occurs at the mouth of a stream. This is due to the faster flowing stream emptying into a slower larger body of water. When deposition occurs at the mouth of a stream or river a process called horizontal sorting takes place. The sediments that were once carried down the stream are arranged from largest to smal
