Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

What circumstances conspired to cause the Dust Bowl? Economic depression coupled with extended drought, unusually high temperatures, poor agricultural practices and the resulting wind erosion all contributed to making the Dust Bowl. The seeds of the Dust Bowl may have been sowed during the early 1920s.

Erosion is the movement of particles away from their source. Example of erosion: Wind carries small pieces of rock away from the side of a mountain. Chemical Weathering: – Decomposition of rock and soil due to chemical reactions.

Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

Some of the most famous examples of erosion include the Grand Canyon, which was worn away over the course of tens of millions of years by the Colorado River with the help of winds whipping through the formed canyon; the Rocky Mountains in Colorado have also been the subject of intense geological study, with some …

Waves washing over rocks on the beach is the correct example of natural erosion because waves from any water body are naturally generated by the effect of wind and gravity these can wipe the surface materials present over the rocks on the beach.

Some examples of physical weathering mechanisms:

• Frost wedging. Frost wedging happens when water filling a crack freezes and expands (as it freezes, water expands 8 to 11% in volume over liquid water).
• Heat/Cold Cycles.
• Unloading.

Examples of Water Erosion

• Canyons. A good example is the Grand Canyon, which was formed by the Colorado River.
• Caves. Flowing water curves out caves over thousands of years.
• Coastal Erosion. When waves hit the shoreline, the impact is sufficient to cause erosion of the coasts.
• River Banks.

These particles move away from the field, and end up in streams and waterways. Three types of water erosion can occur, sheet, rill, and gully.

These are inter-rill erosion, rill erosion, gully erosion, and streambank erosion.

The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth.

The agents of soil erosion are the same as of other types of erosion: water, ice, wind, and gravity. Soil erosion is more likely where the ground has been disturbed by agriculture, grazing animals, logging, mining, construction, and recreational activities.

How to Protect Eroded Land

1. Replant Vegetation Suited to Site Conditions. Well-established vegetation can stabilize the soil in cases of light erosion.
2. Footpaths with Exposed Soil: Cover with Mulch or Gravel.
3. Terraces.
4. Build Check Dams.

Soil Erosion is the process that erodes, breaks or gradually diminishes things down. The process of erosion usually takes place on the surface of soil, rock, or dissolved material from one location on the Earth’s crust and with the help of the wind or water flow, it gets to settle down at another location.

There are two types of erosion: intrinsic and extrinsic.

​The wearing away of the earth’s surface is called erosion. Explanation: Erosion is the phenomenon of the removal of the top layer of the Earth’s surface through the action of agents like air, running water and glaciers.

Erosion is the process by which the surface of the Earth gets worn down. Erosion can be caused by natural elements such as wind and glacial ice. The key to erosion is something called “fluid flow.” Water, air, and even ice are fluids because they tend to flow from one place to another due to the force of gravity.

It is bad when a farmer loses the best, most fertile soil on his land (near the surface) to erosion because this eventually makes his or her land less productive. Erosion also has a good side. Wind erosion and deposition contributed to the development of some of the most productive soils in places like Iowa.

Different Soil Erosion Causes

• 1) Sheet erosion by water;
• 2) Wind erosion;
• 3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
• 4) Gully erosion – when water runoff removes soil along drainage lines.
• 5) Ephemeral erosion that occurs in natural depressions.

Some of the greatest effects of soil erosion include:

1. Loss of Topsoil. Obviously, this is the biggest effect of soil erosion.
2. Soil Compaction.
3. Reduced Organic and Fertile Matter.
4. Poor Drainage.
5. Issues With Plant Reproduction.
6. Soil Acidity Levels.
7. Long Term Erosion.
8. Water Pollution.

Pore water pressure generation during rainfall creates instability among the topsoil surface, which becomes susceptible to soil erosion.

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.

Erosion increases the amount of dust carried by wind, which not only acts as an abrasive and air pollutant but also carries about 20 human infectious disease organisms, including anthrax and tuberculosis.

Water erosion causes loss of topsoil, reduced crop yields, damaged infrastructure, weed dispersal, eutrophication (algal blooms) and silting of dams and natural waterways.

Floods cause erosion because the amount of power that the flow of water brings is often sufficient enough to completely tear away top layers of soil. …

Soil erosion is the result of flooding. Soil erosion can also be caused by the wind. Flooding is the above normal flow of water thru any channel or over land not normally carrying water. Flooding cause soil erosion but soil erosion does not cause flooding.

Water rushes over exposed soil rather than soaking into it, causing flooding. Global warming, the current period of climate change, is speeding erosion. The change in climate has been linked to more frequent and severe storms. Erosion control is the process of reducing erosion by wind and water.

However, floods have enormous destructive power. When a river overflows its banks or the sea moves inland, many structures are unable to withstand the force of the water. Bridges, houses, trees, and cars can be picked up and carried off. Floods can cause even more damage when their waters recede.
