What's the difference between deposition and erosion?

Answer 1

Erosion is the displacement of solids (soil, mud, rock and other particles) by the agents of wind, water or ice, by downward or down-slope movement in response to gravity or by living organisms (in the case of bioerosion).

Deposition, also known as sedimentation, is the geological process whereby material is added to a landform. This is the process by which wind, water or ice create a sediment deposit, through the laying down of granular material that has been eroded and transported from another geographical location.

Deposition occurs when the forces responsible for sediment transportation are no longer sufficient to overcome the forces of particle weight and friction, which resist motion. Deposition can also refer to the build up of a sediment from organically derived matter or chemical processes. For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which has induced chemical processes (diagenesis) to deposit further calcium carbonate.

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 smallest.

Erosion is the displacement of solids (soil, mud, rock and other particles) by the agents of wind, water or ice, by downward or down-slope movement in response to gravity or by living organisms (in the case of bioerosion). Erosion is distinguished from weathering, which is the decomposition of rock and particles through processes where no movement is involved, although the two processes may be concurrent.

Erosion is an intrinsic natural process but in many places it is increased by human land use. Poor land use practices include deforestation, overgrazing, unmanaged construction activity and road or trail building. However, improved land use practices can limit erosion, using techniques like terrace-building and tree planting.

A certain amount of erosion is natural and, in fact, healthy for the ecosystem. For example, gravels continually move downstream in watercourses. Excessive erosion, however, can cause problems, such as receiving water sedimentation, ecosystem damage (including dead fish) and outright loss of soil.

Answer 7

They are opposites.
Erosion is when the soil or rocks wear away. This could be by wind or rain, for example.
Deposition is when a building up occurs. This could be by silt in a river building up at the mouth of the river into a delta, for example.
If you went to a place where there was an ancient ocean, you could see the layers that have been built up and worn away in the sides of the hills.

Answer 8

When we talk about deposition we talk about sediments of rocks and rocks with vegitation being moved to another place or being put into a curtain form e.g deposited in layers...and erosion means, rocks and and curtain things in the eviroment being worn away or being broken down...

Answer 9

Erosion is when the land is scraped by winds,water, and ice sheets which are called glaciers. Deposition is when the winds,water,and glaciers put the land to another piece of land. : )

Answer 10

erosion is to take away heres one more thing weathering is to take apart
