What is the difference between erosion weathering and deposition

Another form of physical weathering occurs when wind or water causes rocks to rub against each other, smoothing their surfaces. For example, iron in a rock might react with oxygen to form easily degradable rust, or acids in rainwater may remove calcium from limestone and marble. Chemical weathering often precedes physical weathering, making rocks more vulnerable to forces like wind and rain.

Different types of erosion are usually differentiated by the force that carries rock, stone or soil away from its location. Water is the most common force that causes erosion. Rivers wear down and carry away rock and soil along their banks. The Grand Canyon was formed from millions of years of this sort of erosion.

Similar erosion occurs in the ocean, where moving water and waves degrade and carry away particles of coastline rock. Wind erosion can only occur on smaller particles of ash, dust and rock, but it can still move large quantities of these particles from their original locations and create impressive formations, such as sand dunes. Erosion by ice is rare in most parts of the world, but ice can move much larger rocks than most other erosive forces. Ice may carry huge boulders miles away from their original locations.

Mass wasting occurs when soil or rocks are carried away - not by wind or water - but by falling or sliding downwards. A study on coastal erosion and deposition processes in subang, Indonesia.

What is Erosion? Erosion by ice — Glaciers erode the surface of the Earth in two ways: Plucking and Abrasion Erosion by water — Sediment, picked up by flowing water, is moved along in one of four ways: Traction, Saltation, Suspension and Solution. Erosion by gravity — Soil creep, mudflows, landslips and Rockfalls What is Deposition? Difference between Erosion and Deposition 1. Definition Erosion Erosion is defined as wearing away of rock along the coastline.

Deposition Deposition is a process in which sediments, knocked rock pieces, and soil are carried by wind, gravity and water and deposited in a new location to a landform or land mass. Types Erosion The 4 main types of erosion are Abrasion — When pebbles grind along the river bank and bed in a sand-papering effect. Hydraulic action — This is the sheer power of the water as it smashes against the river banks. Air becomes trapped in the cracks of the river bank and bed, and causes the rock to break apart.

Solution — happens when sea water dissolves certain rock types. Attrition — takes place when sea carries the rocks and these rocks knock against each other. As a result, they break apart to become more rounded and smaller. Pollution and Poor Water Quality Deforestation and Flooding Soil Degradation Mudslides and Structural Problems Deposition Rivers and streams fill with melting snow in the springtime Water vapor changes directly to ice without first becoming a liquid Sediment deposition destroys fish spawning beds Reduces the useful storage volume in reservoirs, clogs streams Carry toxic chemicals 4.

Occurrence Erosion Erosion occurs when: There is a loss of plant cover, which increases the amount of soil lost to wind and water erosion Delta is formed at the mouth of the river Plant roots crack a parking lot Ice freezes and cracks rocks. They break into smaller pieces Deposition Deposition occurs when: Water carrying the sediment slows down The glacier carrying the sediment melts The wind carries the sediment dies down Beach gets washed away by a hurricane Sand dunes are blown away by a wind Rocks are broken down into soil 5.

In science erosion is defined as :. Weathering and erosion both involve rocks, but there are three main differences between these two processes. Take a look at examples of weathering and examples of erosion side by side in a chart to see the slight differences between them. Deposition is the opposite of erosion in science. Processes like weathering, erosion, and deposition shape the natural world you live in.

Mechanical weathering physical weathering makes rocks crumble. Chemical weathering changes rock or soil molecular structure.
