What is Erosion — Definition, Characteristics, Types 3. Erosion, Rocks, Minerals, Weathering. Weathering is the geological process of breaking down resources such as rocks and minerals due to the contact with the atmosphere, water, or biological organisms. Unlike erosion, weathering is an in situ process; this means, it occurs at the same place where the source lies on, and there is no movement.
There are two types of weathering as chemical weathering and physical weathering. Sometimes, these processes may include biological components as well; e.
In physical weathering process, breakdown of rocks and soil occurs due to the direct contact with mechanical conditions such as heat, water, ice and pressure.
Chemical weathering is caused by direct atmospheric chemicals or biological components. Physical weathering mostly occurs in very cold or very dry areas. In contrast, chemical weathering occurs in very wet and hot areas. After the completion of a weathering process, the leftovers combine with organic matter to form soil.
Erosion is a geological process that involves the transportation of geological sources from one place to another due to surface processes such as water flow.
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.
Mass wasting may also cause physical weathering by causing rocks to shatter upon hitting the ground or causing rocks to rub against each other while rolling and sliding.

Zamboni has a Bachelor of Arts in religious studies from Wesleyan University. What Are the Two Types of Weathering?
What Factors Determine the Rate of Weathering? What Are the Agents of Weathering? What Are Examples of Mechanical Weathering? Bioerosion - Plant growth breaks up and moves soil or rocks. Ice erosion glacial erosion - Glaciers moved by gravity carry sediment away.
Liquid water erosion - Rain and bodies of water carry or wash away sediment. Mass wasting - Rocks and soil are moved downward from events like landslides. Wind erosion - Wind carries sediment away. Main Differences Between Weathering and Erosion Weathering and erosion both involve rocks, but there are three main differences between these two processes.
Weathering Erosion happens at site of rock or mineral happens away from original location does not involve movement of materials involves movement of materials breaks down rocks and minerals moves and deposits rocks and minerals.
Examples of Weathering and Erosion Take a look at examples of weathering and examples of erosion side by side in a chart to see the slight differences between them. Weathering Erosion large rocks in a river being broken down pebbles rolling along a river bed sand-sized particles of a rock breaking off their original source grains of sand suspended in and moving with wind fragments breaking off a large deposit of rock salt salt suspended in ocean water and moving with currents.
