What Does Erosion Do? ›

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide.

In his studies, Wheeting found natural amounts of soil erosion helped feed water sources with essential nutrients, helping the local aquatic ecosystem. The erosion also helped cleanse the soil of any useless materials, such as rotting tree matter or nutrient-less dirt from the area.

Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.

Advantages of soil erosion are; nutrient distribution, vegetation stabilization, soil detoxification, landform modification, and geochemical cycling.

Answer and Explanation: Natural erosion is a beneficial process for several reasons, most notably that it deposits new quantities of soil throughout ecosystems to provide replenishment.

Soil erosion reduces the quantity and the quality of soil ecosystems and arable land (land that can be used to grow crops).

Soil erosion, transport, and deposition are integral parts of the global sedimentary cycle and are important to altering and balancing the water- and nutrient-holding properties of soil profiles and transporting nutrients and sediment in and through rivers, reservoirs, estuaries, or deltas (see figure below).

Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another.

When it rains in my backyard, the rain carries the soil to the edge of my backyard near the fence and creates a huge mud puddle. This is the process of moving soil to a new location, which is called erosion.”

DEFINITION OF EROSION. Erosion is when tiny pieces of the Earth's surface are moved from one place to another. This is usually caused by moving water or wind.

The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Depending on the type of force, erosion can happen quickly or take thousands of years. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.

Sometimes erosion can happen very quickly like with mudslides. Mudslides are caused by moving water and gravity, and happen in only minutes. Most weathering, however, is a slow process that happens over thousands or millions of years.

Water erosion

Moving water is the most important natural erosional agent.

Depending on the type of force, erosion can happen quickly or take thousands of years. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.

moving water is the major agent of the erosion that has shaped Earth's surface. It also builds up the surface through deposition.
