Can different types of plants prevent soil erosion? Erosion is the wearing away of land by wind and water. It can be caused by frequent and intense rain, high river levels, strong storms and fast moving streams. Erosion can also lead to a variety of environmental issues. Plants are a natural way to help prevent erosion and other environmental issues caused by erosion.
There are two main types of erosion, wind erosion and water erosion. Both these types of erosion include soil detachment, soil movement and soil deposition. Also, these types of erosion can happen rapidly or slowly. Wind erosion is caused by soil erodibility, soil surface roughness, climate, unsheltered distance and vegetation coverage. This means that when soil surfaces are …show more content…

It can cause natural disasters such as landslides. Landslides can be deadly, and they can alter the landscape of the Earth. In the 20th century there were at least seven catastrophic landslides caused by heavy rain, leading to erosion. For example, in Brazil in 1967, 1,700 people were reported dead due to landslides and flooding. Erosion can also cause other problems such as soil degradation. Soil degradation is the decline of soil condition. An example of a natural cause of soil erosion and degradation is the flow of rivers. Soil erosion from some agricultural areas may be as large as 300 tons per hectare per year (Earth Science for Students). This leads to soil degradation which can then lead to large economic losses. According to the U.S. Department of Agriculture, the U.S can spend as much as 10 billion dollars a year due to erosion. Soil degradation is also a problem in developing nations. The loss of soil can lead to desertification, the spread of desert conditions. A third problem that can be caused by erosion is water pollution leading to the death of aquatic life. Eroded soil can contain pesticides and fertilizer that can be deposited into rivers, dams, wetlands and other waterways, causing pollution. Also, the soil that erodes will then change into sediment. Sediment is matter that settles at the bottom of liquid. The chemicals that erode into the water can cause excessive algae to grow, while the sediment makes it difficult for aquatic plants to perform photosynthesis. Both chemicals and sediment cause the death of aquatic life, including fish, invertebrates and

  • Coastal Erosion In Louisiana

    684 Words  | 2 Pages

    Coastal erosion is a growing problem along the Gulf Coast. Louisiana is one of the coastal states most affected by coastal erosion. Ninety percent of wetland loss in the nation occurs in Louisiana, losing 25-35 square miles per year. At that rate, Louisiana will lose 640,000 more acres by 2050. Many factors contribute to this land loss, such as rising sea levels, subsidence, hurricane storm surge, cold fronts, and human interference. Cold fronts and hurricanes can both have detrimental consequences on the coast of Louisiana (Zhang 2004) (Restore or Retreat 2012). This research shows whether cold fronts or hurricanes have a larger effect on coastal erosion. The researcher will describe how historical and current satellite imagery help in determining the changes in the Louisiana coast. Based on previous research, the researcher believes that hurricanes have more of an effect on coastal erosion than cold fronts due to the high winds and storm surge.

  • Mudslides: Causes and Effects

    521 Words  | 2 Pages

    Mudslides usually occur in hilly areas, for an example, when there was a mudslide in Bangladesh few months back, it occurred at Chittagong. Mudslides occur when a portion of a hill side becomes too weak to hold up its own weight. This is generally caused by an intense amount of rain fall. With all of the new water introduced into the slope the content of liquid makes it so heavy that gravity pulls it downward. Although water plays a major factor in creating the mud that flows in a mudslide the real reason that the land begins to slide is gravity. What happens is mudslides redistribute soil and sediments in a process that can be in abrupt collapses or in slow gradual slides.

    More specifically, forest, soil, aquatic life, and public health. Acid rain gets rid of minerals and nutrients from soil that trees need to legitimately grow. Trees influenced by corrosive rain are weakened and develop slowly. They become frail and are prone to be harmed by ice, creepy crawlies and illnesses.("Understanding Acid Rain" S1) Acid rain harms leaves and at this point, they can no longer utilize photosynthesis adequately to make enough food to keep a tree developing.(Reich and Amundson 566) Soil is a dynamic blend of rock and rotting matter that covers a large part of Earth 's surface. Soil is necessary, it provides many resources. Acid rain may seep into soil, causing it to mix with the soil. Calcium and magnesium are vital for plant development, they also kill acids, by the use of buffering. After some time the soil begins thin and can turn out to be progressively acidic, due to the rain. Acid rain usually falls right over bodies of water. As time goes on the chemicals in the rain affect the overall pH of the lake, stream, or river. If the pH drops the aquatic life would suffer, it lowers the amount of biodiversity. () Dry forms of acid rain can cause health problems like bronchitis and asthma. Acid rain damages our

    When people think of geology, they usually think of rocks and fossils. However, geology is actually a very large field of study. The knowledge of geologists ranges from rocks and fossils to the moon and other planets (Hammonds 7-8). Geologists use a variety of subjects in their work, but the sciences and math are the most important. Some of the sciences geologists study are physics and chemistry (12). English is also a subject that geologists use when communicating with other scientists, the media, and the public (12) . Because of these tasks, it is important for geologists to have a wide knowledge of these different subjects.

    There are several causes of acidification, and various mechanisms by which it may occur. Acid rain falling on water bodies has a direct affect. In areas where soils are acidic, runoff from the soil transports acidic water, which may also contain aluminum, into lakes and rivers. Soil acidification may be caused by acid rain, but other factors may also be involved. For example, if pasture reverts to coniferous acidic runoff even though the rain itself is not acidic. Salty rain leaches acid components out of the soil and transports them to the rivers. (Rivers 1)

    Planting trees and certain other herbaceous plants can have a significantly positive impact on the mitigation of soil erosion. Some great plants that are useful when trying to control soil erosion are sage, buckwheat, and oak trees. This will help keep the water from soiling up and another way is that wrappers, bottles and other trash are unfortunately a common sight at many well-used beaches and rivers around the world. It should be obvious that the trash from these places often ends up in waterways and can cause pollution. Plastics are an especially big issue when it comes to water contamination at beaches and waterways.
