rocks to form caves and to move rock and soil to other places. By doing this is causes major erosion. Erosion is very bad because it slowly breaks away soil‚ and takes out all the nutrients that plants need to survive. Below is a picture of a rain drain next to a road and is where all the run off from rain goes. Natural actions can affect the Earth’s surface in many ways. Things such as weathering and erosion causes plants to die. Things that cause this is water‚ wind‚ and ice. Soil formation could

resulting in accelerated soil erosion in most camps. The problem was further aggravated by the onset of the rainy season. While erosion could be observed in and around refugee camps in Goma‚ the problem was very serious‚ and often critical‚ in the camps around Bukavu‚ which were often on steep slopes and on alluvial soil. Absence of terracing and proper drainage channels‚ as well as a near-total destruction of vegetation of theses slopes by the refugees‚ meant serious erosion and formation of ever-deepening

With having the beauty of technology we can go on NOAA’s website and actually find the tide level for the certain time and day we need for our data. Other tools we use are measuring tape‚ a sand grain size chart‚ and cameras. A lot of the beaches on Saipan have vegetation which helps us identify erosion and accretion. Examples of erosion are

pesticides may contaminate water supplies; more intensive farming and the abandonment of fallow periods tend to exacerbate soil erosion; and the spread of monoculture and use of highyielding varieties of crops have been accompanied by the disappearance of old varieties of food plants which might have provided some insurance against pests or diseases in future.

Madagascar has one of the highest soil erosion numbers recorded in the world at 112 tons per acre annually (wildmadagascar.org‚ 2007). This is particularly difficult for an island whose number one source of income is agriculture. The severe loss of soil and nutrients has its affect on agriculture
