can nyone list three factors that increased soil erosion.?

Vegetation is probably the most important physical factor influencing soil erosion. A good cover of vegetation shields the soil from the impact of raindrops. It also binds the soil together, making it more resistant to runoff. A vegetative cover provides organic matter, slows runoff, and filters sediment. Deforestation is of course a huge factor in this case.\n\nThe climatic factors that influence erosion are rainfall amount, intensity, and frequency. During periods of frequent rainfall, a greater percentage of the rainfall will become runoff. This is due to high soil moisture or saturated conditions\n\nTemperature is another climatic factor influencing erosion. While frozen soil is highly resistant to erosion, rapid thawing of the soil surface brought on by warm rains can lead to serious erosion. Temperature also influences the type of precipitation. Falling snow does not erode, however, heavy snow melts in the spring can cause considerable runoff damage. \n\nTemperature also influences the amount of organic matter that collects on the ground surface and incorporates with the topsoil layer. Areas with warmer climates have thinner organic cover on the soil. Organic matter protects the soil by shielding it from the impact of falling rain and soaking up rainfall that would otherwise become runoff.\n\nin conclusion the change of any of these will increase it, the primary cause is of course vegetation cover and deforestation, canopy coverage and gradient run off.... the less trees, the quicker the soil erosion, the more minerals in the soil, the slower soil erosion.\n\ni hope this answered your question

Depends on the soil and what chemical process was used, but mostly plant nutrients. Very helpful website below.

The simple answer is, of course, rain. I suspect, however that you're really supposed to undertake a bigger project, and explain the overall causes of the dust bowl and why normal amounts of rain led to flood condtions.\n\nYou should start by using some of the excellent resources that are on the web that explain how farming practices, weather, migration, and other factors all are interrelated.

Water, wind and ice can all cause erosion in rocks.  Wind will often blow small bits of sand or pebbles at a rock, which can wear it down.\nWater does something similar, slowly wearing down a rock over time.  This is why you often find round stones in and around rivers.\nWater also gets into the cracks of a rock.  As the water freezes, it expands and causes bits of the rock to break off.

Forest cover tends to create areas of groundwater recharge and generally slows runoff. Trees tend to buffer the speed which rainfall hits the ground and because they often create areas covered with organic material like leaf litter, the ground has more time to absorb rainfall before it runs off. Bare ground will be subject to erosion as well as higher rates of runoff. \n\nThe burning of trees may contribute to CO2, but is probably insignificant because it is a one time event. The removal of the trees is likely to be accompanied by a long term loss of soil organics, which will also contribute CO2 over time. The real change may be through albedo effects and changes in rainfall related to loss of trees may be an even bigger factor. In Brazil,when trees were removed to be replaced with even darker colored soil, the average temperature of the area increased by about 3 degrees C. Most cities have a heat island around them, often 10% warmer, due to changes in albedo. The lack of trees may change the rainfall patterns, and some hypotheses actually predict that even rain drop size may change. A study in Amazonia known as the Large Scale Biosphere-Atmosphere Experiment is investigating these ideas.

Mudslides(flows can be helped and are caused from \nlack of plants,roots ,brush,trees ect on the sides of hills.With the escavation and creation of new\nhousing ect and for the clean hillside look.The\nimportance of the undergrowth of grass ,trees ect \nhave been depleted and not replaced.They have \nprograms for beaches and hillsides,even in foreign\ncountries that realise the importance of root and plant systems in hillside lands.The winding and \nweb patterned root systems of these plants,trees\nacts like a "net" and the plants themselves and erosion barrier.

(1) There are several factors which make environmental problems. Some of them are mentioned below for your knowledge.\na) Overcrowding, poor-quality housing\nb) Inadequate provision for water supply\nc) sanitation factors\nd) Different pollutions( air, water, land)\ne) Deforestation\nf) Smoke from vehicles and  factories\n\n(2) In addition to that, secondary impacts of the above mentioned factors are also make environmental problems.

The wind blows sand and rubble. Erosion might also cause the land to shift.

1) The continued loss of Family farms, and the increase in Corporate farms.\n2) Advances in automation of farm machinery.\n3)Changes in chemicals used in fertilizer.\n4) Genetic engineering ans opposed to hybredization.\nIn 3rd world countries in Africa and South America war and global warming have increased the loss of rain forest by 'slash & burn' significantly.

Water...\n\n* Liquid water, eg in rivers and coasts (in the sea this is largely caused by the gravitational effect of the moon);\n* Liquid water is a major cause of landslides - soil becomes over-saturated and therefore loses its adhesion to the soil or rock beneath;\n* The action of freeze-thaw where liquid water seeps into cracks, expands when it freezes thereby widening the crack and ultimately splitting rocks apart;\n* Frozen water in the form of glaciers grinding away at mountains;\n\nOther causes of erosion include:-\n* the wind, especially when it blows sand particles with it which erode rocks;\n* the Sun which alternatively heats and cools rocks so that they split in much they same way as freeze-thaw (especially in desert areas);\n* humans - we contribute to many of the above processes by our own actions, eg deforestation prevents the soil from holding as much water so landslides become more likely; over-farming creates deserts which are subject to wind and sun; coastal "management" often results in more rapid erosion of some areas of coastline

Erosion breaks up igneous and metamorphic rocks, and the particles build up to create sedimentary rocks.  \n\nHope this is helpful.

Yes, soil moisture.\n\nBut how about the degree of ionicity of the soil; wouldnt that depend on the kinds of minerals in the soil (which is likely to vary as well)...\n\nCordially,\nJohn\nhttp://www.GodSci.org

There's entirely too much information available on this subject.  I suggest you start with a simple internet search with using words or phrases like 'tropical deforestation issues' or 'impact of tropical deforestation'.  There's a ton of info to find.  Also try your local library.  I'm sure there are tons of magazine and journal articles written on the subject.
