The denudation of the soil cover and subsequent washing down is described as soil erosion. The processes of soil formation and erosion, go on simultaneously and generally there is a balance between the two. Sometimes, this balance is disturbed due to human activities like deforestation, over-grazing…, construction and mining etc., while natural forces like wind, glacier and water lead to soil erosion. breaking down of soil time period can cause land slides.

Soil erosion is not the same as soil transfer. Soil erosion is when an element (ie: wind, water) erodes the soil, taking it away. Soil transfer is when an element (ie: wind, water) carries (transfers) soil to somewhere else, depositing it.. Soil erosion is caused when underlying factors disturb the… dormant soil. Examples include a flood where the water rushes in and washes soil out or an underground pipe bursts. Also if too many trees are chopped down in a hilly area, it will eventually cause erosion. . Soil transfer, commonly seen in deserts, is caused when high winds lift up and carry the soil away, depositing it many miles away. This is also seen in the southern states and South America, where storms bring dirt and sand all the way from the Asian or Mediterranean regions. (MORE)
Soil takes a long time to build up, and without it, many plants cannot survive. Without plants, there can be very few insects or other animals that can live there.
Soil erosion is a naturally occurring process - just because it happens does not necessarily make it something that should be prevented. It's what you intend the soil to be used for or if there are any consequences to soil eroding in the area that makes prevention important. Soil may be used as a… support for something - earthen dams for instance. If the soil that composes a dam starts to erode, it strongly affects the integrity of that dam. If too much damage were to occur and the dam's reservoir were to fill up too much, the erosion would make it much easier for the dam to break, potentially flooding the downstream area and causing damage to property, infrastrucute, and possible loss of life. Similarly, if soil erosion were to occur over time, it could change the course of a river or stream - this could be very bad if the new stream flows over a town or series of roads. In the same way that soil erosion could lead to disasterous effects for things we consider convenient, it's just as possible that the events that take place after excessive erosion could involve damage to the habitats or eradication of animals in the area. Or perhaps you have a garden you want to keep looking nice! The nice part about erosion is that it takes a little more time for something serious to occur - even though erosion may be hidden under the ground. This is called a sink hole when exposed - you wouldn't want these to develop underneath a street or sewage drain since that soil acts as a suppport for keeping such things in place! (MORE)
Soil erosion is a serious agricultural issue. It has, in the past, contributed to environmental problems, such as the Dust Bowl of the 1930s. In contemporary times, farmers have a couple of options they can take to reduce soil erosion: . Planting wind-rows - wind rows are columns of, typically, …plants that surround the fields, in order to break the wind, and reduce soil erosion. . Contour plowing - a form of plowing that involves concentric, sloped fields instead of steps (this reduces topsoil exposure, and thus, reduces soil erosion). . No-till farming - by replacing the act of plowing (which removes weeds), with heavier use of herbicides, roots are not disturbed, and soil erosion is minimized. However, this is done at the cost of increased chemical runoff. (MORE)
Erosion is the process of weathering and transport of solids (sediment, soil, rocks and other particles) in the natural environment or their source and deposits them elsewhere. It usually occurs due to transport by wind, water, or ice; by down-slope creep of soil and other material under the force …of gravity; or by living organisms, such as burrowing animals, in the case of bioerosion. Erosion is a natural process, but it has been increased dramatically by human land use, especially industrial agriculture, deforestation, and urban sprawl. Land that is used for industrial agriculture generally experiences a significantly greater rate of erosion than that of land under natural vegetation, or land used for sustainable agricultural practices. This is particularly true if tillage is used, which reduces vegetation cover on the surface of the soil and disturbs both soil structure and plant roots that would otherwise hold the soil in place. However, improved land use practices can limit erosion, using techniques such as terrace-building, conservation tillage practices, and tree planting. A certain amount of erosion is natural and, in fact, healthy for the ecosystem. For example, gravels continuously move downstream in watercourses. Excessive erosion, however, causes serious problems, such as receiving water sedimentation, ecosystem damage and outright loss of soil. (MORE)
In the short term (a human lifetime), yes ... if the ground isn't too vertical. In the long term, everything gets worn down to the sea (and the pushed back up via volcanios.
we to fix erosion u put a roof over what u don't wont to be eroded
Plants' roots hold soil in place. When the plants are gone, so is the soil. They Mean True Or False !
soil erosion occurs when the surface of the soil is being washed away by erosion agents such as wind, rain, flood etc.
Causes : gravity, rain, flooding, wind, drought, deforestation, farming, flowing ice, the loss of vegetation after a major forest fire, uncontrolled land use, and poor agricultural and forestry practices Effects : desertification, additional sedimentation, loss of habitat, infertile soils, inc…reased use of soil conditioners and fertilizers, water pollution (MORE)
No, they are not the same. Soil degradation is when soil deteriorates because of human activity and loses its quality and productivity. It happens when soil loses its nutrients, or its organic matter. It also happens when the soil structure breaks down, or if the soil becomes toxic from pollutio…n. Soil erosion is when the soil is washed or blown away by water or wind. It is often caused by human activity, like tree felling and clearing vegetation from the land. (MORE)
Erosion can be prevented by maintaining plant growth in an area, and stopping is simple: don't put anything into the ground.
Soil erosion carries top soil away, which is troublesome if were hoping to grow plants there.
Because the conditions that hold it together is disturbed and it is easily washed along by water. theincreased surface exposed to the air also tends to dry it out making it more prone to blown about by the wind.
soil erosion damages the soil because it does not let plants grow well when topsoil is removedgcv
because it very simple we need it for a lot thing for trees ,plats ,fruit and vegetables
Yes, extensive and uncontrolled grazing causes soil erosion. It clears vegetation from the land and hence there is nothing that can stop the soil from being eroded away.
Soil erosion may not necessarily cause landslides but landslidescan be a side- effect or result of soil erosion and mass wasting.
yes because as we mine, the top soil is washed away and this makes the soil in-fertile.
Mass Movement (Landslips and Slumps) Mass movement involves the downward movement of soil and rock under the assistance of gravity Water Erosion Water erosion is a two-part process involving the detachment and transport of soil particles. The water erosion process consists of discrete stages fro…m rain drop impact to the formation of gully erosion. Each stage has its own processes and characteristics. Controlling or preventing water erosion requires an understanding of each step in the erosion process. Wind Erosion Wind erosion involves the detachment, transportation and re-deposition of soil particles by wind. Wind erosion is common on flat, bare areas with dry, sandy soils, or anywhere the soil is loose, dry, and finely granulated. Sandy soils are very susceptible to erosion; however clay soils which have been pulverized by powered tillage implements or worked when they are too dry are also susceptible to wind erosion. (MORE)
Earth, by far, though Mars shows indications of a condition that at least appears to be soil erosion.
we need to conserve soil because it is a vital part of the ecosystem. soil is necessary for the proper growth of plants. it also helps to purify underground water.
because rain is a part of the 4 agants water is one of them and rain will take dirt away
When livestock graze an area repeatedly without letting the grasses have enough time to grow back, they destroy not only the plants themselves, but also the root system. When the root system is depleted, and when the plants are grazed so close to the ground, the soil is exposed to the wind and rain,… and makes it easier for the wind and rain to lift the soil up and carry it away.

steep slops, melting snow, heavy rain, increase in animal number, unstable soil, trees for firewood, population increase and Terraces collapse.
plants such as grass, trees, and clovers have roots that grips on to the soil and stops it from moving when it rains. that is why you see grass on farmlands when not in use.
By grazing too close to the earth too often exposes the soil to the winds and rain.
Soil erosion can not be completely prevented but it can be greatly reduced. Clearing land removes vegetation and tree roots that hold the soil together. Some farming practices leave great tracts of land open to the winds that can blow the topsoil away, sometimes for thousands of miles. Clever and… careful replanting is one answer to prevent soil erosion. (MORE)
The wind isn't so weak as you may think. In the deserts and places the wind shapes the sand and caries small particles of sand through the air. This slowly and effectively changes the shape of structures bit by bit.
\n. soi\n Soil erosion is many things but, it is mostly the washing away of soil by the elements. Soil is naturally removed by the action of water or wind. Other causes of soil erosion can be plowing, deforestation, animal interference, and the landâs topography.
Workplace hazard assessment and control is the process of identifying hazards in the workplace and eliminating them or reducing either the probability they will occur or their likely consequences.
soil erosion can affect the soils fertility and it's ability to grow plants,because the fertile soil was carried away by the water .in this case ,the farmer will be affected because of a low production due to soil's infertility.
in my point of view,the basic cause of soil erosion is water . this has tremendous soil cutting capacity due to various small particles and high speed of water flow.This high speedy water carries the upper- most fertile layer of earth crust needed for successful plant production. The other major… cause for erosion is Wind .This ; carries the upper portion of soil up to a depth of 15mm and then a barren land is left.Heavy rains are also a cause of soil erosion.Soil erosion is mainly protected by growing tress , which capture the soil and do not allow it to move away.

Simply by not having sufficient irrigation and by destroying the topsoil thus leaving the ground to the wits of the winds.
People (farmers) used to contribute heavily to erosion by plowing under their fields in the fall. The current practice of "no till" (letting crop residue stand over the winter) has greatly decreased erosion because the root systems of dead crops hold the soil in place until the following spring.
Soil Erosion affects the land in many ways. It can take away the topsoil of the soil horizon which is important to growing crops and pasture for its organic matter. Also erosion can cause leaching of the soil which means that nutrients leave the soil and may become hazardous to aquatic life downstre…am. (MORE)
Erosion is the movement of weathered(broken down by water, wind, etc.) material. Soil erosion changes soil because it takes away nutrients from it. This in-turn makes the soil unhealthy which affects it's living organisms such as plants. This can affect us because when we eat the plants that are f…rom the unhealthy soil, we are receiving less nutrients. Edit: Soil erosion also changes the soil by simply removing it. Many tons of soil are lost every year due to erosion by wind or water. This soil may end up at the bottom of the ocean, or other places where it will never do anyone any good. Soil that is well-rooted with perennials like grass or trees, etc. does not erode. Erosion is mostly due to the practice of tillage in farming. Low-tillage, or no-tillage methods of farming greatly reduce the losses of soil due to erosion. (MORE)
Deforestation results in soil erosion because the usual trees that were holding the soil in place has been destroyed causing the area to be easily infiltrated by various types of erosion factors
Preventing erosion isn't difficult. The best thing you can do is plant. Plant grass, flowers, trees, etc. When you plant things their roots dig down into the soil and hold it together it is very efficent. Also you can make a barrier with large rocks but that will only be a small fix until you plant …things. If the soil is bad and you can't grow things add fertilizer, compost, some potting soil, and other things to get the soil good, and you can get a Ph test to see if you need your soil more acidic or more basic (MORE)
Soil erosion looks like soil being moved away for example:like you pour a cup of water on rice see how the rice moves ,soil erosion is something like that! .
they absord the minerals and nutrients from the soil, which leaves it weak- i think
The effect of soil erosion on earth is that it leads to the removal of fertile soil. It leads to the lessening of water holding capacity of soil.
The obvious danger is the possibility of an inaccurate assessment. If the actual risk is greater than the assessment , proper prevention may not occur and unnecessary damage may occur. The assessor may also be blamed for not giving an adequate warning of a danger if an accident occurs. On the othe…r hand, if a risk is over-rated an over-reaction may occur. Relatively safe practices and devices have been banned in the past by governments at needless expense to businesses and individuals and sometimes the proposed substitutes not only are more expensive but do not work or work poorly.

The conclusion of soil erosion is that no soil remains in theoriginal location. It has all moved into the water area, which cancause these areas to become smaller.
Yes plants prevent soil erosion in many ways.One of the way is by its roots,as the root grow longer they bind it with the soil and help the soil from getting errodded.
The rate of erosion depends on many factors. Erosion is caused by "fluid flow". Any substance, like water, wind, or ice, which flows consistently from one place to another, will facilitate erosion. The geologic factors include the sediment or rock type, its porosity and permeability, the slope (grad…ient) of the land, and whether the rocks are tilted, faulted, folded, or weathered. The biological factors include ground cover from vegetation or lack thereof, the type of organisms inhabiting the area, and the land use. (MORE)
beauase root hold the soil and prevent from soil erosion. I think soil erosion is not desirable for agriculture. What is desirable about losing your soil. Soil is essential for agriculture and if you lose soil then you can't do agriculture.
By terracing, contour plowing, natural vegetation, strip cropping, using trees as windbreaks, reforestation and afforestation.
