What is the difference between eroding and weathering

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. Weathering vs.

Erosion vs. Deposition Deposition is the opposite of erosion in science. Another form of physical weathering happens when wind or water makes rocks rub against one another, smoothing their surfaces. Chemical weathering changes the chemical structure of rock, making it become milder or increasingly brittle. For instance, iron in a rock may respond with oxygen to form effectively degradable rust, or acids in water may remove calcium from limestone and marble.

Chemical weathering regularly goes before physical weathering, making rocks progressively defenceless against forces like breeze and downpour. Types of Erosion. Various sorts of erosion are normally separated by the force that conveys rocks, stone or soil away from its location. Water is the most widely recognized force that causes erosion.

Waterways wear out and carry away rock and soil along their banks. The Grand Canyon was formed from a great many long stretches of this kind of erosion. Comparable erosion happens in the sea, where moving water and waves debase and carry away particles of coastline rock. If you read this far, you should follow us:. Diffen LLC, n. Erosion vs. Comparison chart Erosion versus Weathering comparison chart Erosion Weathering Definition Erosion is displacement of solids soil, mud, rock and other particles usually by the agents of currents such as, wind, water, or ice Weathering is the decomposition of rocks, soils and their minerals through direct contact with the Earth's atmosphere.

Small particles of rocks, soil Movement Movement of eroded material occurs Movement of weathered material does not occur. External causes Wind, water, ice, humans etc. Atmospheric conditions like air, pressure etc. Wind, Rain, Water from garden hoses, freezing temperatures, etc. Factors Erosion occurs because of factors like wind, water, ice, human activities like deforestation etc.

Movement Erosion is caused by the movement of eroding agents while in weathering there is no movement. Types Weathering is broadly categorized as follows: Physical or Mechanical Weathering Mechanical weathering is the cause of the disintegration of rocks.

These can further be classified in the following: Thermal Expansion : Thermal expansion, also known as onion-skin weathering, exfoliation, insolation weathering or thermal shock, often occurs in areas, like deserts, where there is a large diurnal temperature range.

Freeze Thaw Weathering : This type of weathering is common in mountain areas where the temperature is around freezing point. Frost induced weathering, although often attributed to the expansion of freezing water captured in cracks, is generally independent of the water-to-ice expansion.

Frost Wedging : Frost action, sometimes known as ice crystal growth, ice wedging, frost wedging or freeze-thaw occurs when water in cracks and joints of rocks freezes and expands. Pressure Release : In pressure release, also known as unloading, overlying materials not necessarily rocks are removed by erosion, or other processes , which causes underlying rocks to expand and fracture parallel to the surface.

Causes for erosion include dynamic activities of erosive agents such as water, ice, snow, air, plants, animals and people. Figure 2: Erosion due to Water Flow. There are different types of erosion, depending on the causative agent—for example, water erosion, wind erosion, snow erosion, zoogenic erosion, and anthropogenic erosion.

The rate of natural erosion mainly depends on the rainfall, bedrock wear in rivers, sea waves, etc. Typically, the erosion rate is higher at steep landscapes. Generally, erosion takes place as a natural process, but sometimes it is artificial; e. Artificial erosion is greater compared to natural erosion, and it shows a greater impact as well. There are four subtypes of water erosion: splash erosion, sheet erosion, rill erosion and gully erosion.

At the first stage of an erosion process, splash erosion occurs, which is followed by sheet, rill and gully erosion processes.
