Today we are going to learn five facts about soil erosion fact. Number one. There are four main types of soil erosion erosion is a disruption and displacement of the soil on the ground, which may be moved by water wind or human interference. There are four main types Splash erosion. This is when water usually rain drop hits soil and coves it to be displaced. Sheet erosion. This is when sheets of water flow over land carrying the soil with it rail erosion. This is when running water creates small channels, like tiny Rivers which travel through soil and create gaps in the soil where the water run through and golly erosion.
This is the most drastic form of erosion. It is a much larger form of rill erosion where running water creates gullies like a small Valley in the soil fact number two soil erosion affects the top soil top soil is a very important part of the earth, it contains all the important nutrients and minerals needed to grow crops the top soil also absorb some moisture and prevents flooding Farmers plants seeds in the top soil the grill healthy. Needs which are full of nutrients fact number three plants are a great defense against soil erosion.
This is especially True by the sides of rivers or lakes where erosion is caused by water the roots of the plants dig deep into the ground and trapped the soil in place meaning that it cannot be eroded away. If you are by the side of a river, you might see trees with exposed roots which are holding back to soil soil, which is loose can also be carried away by wind and tall trees are helpful in preventing this by planting tall trees shrubs and bushes. The wind is stopped or slow down before it reaches the soil preventing the soil from being blown away facts number four soil erosion.
How Farmers grow their crops crops don’t have to be grown on flat ground many farmers grow crops on hills and raised grounds, if their crops are grown on a slope they have to work extra hard to prevent soil erosion from damaging the growth of their crops farmers use a clever technique which prevents the soil from being eroded instead of planting their crops in lines, which grew up and down the slope. They grow their crops in lines, which go across the slope. These lines are called contour line and they prevent soil from being swept down the slope and away from the crops.
fact number five soil erosion can cause dust storms soil which does not have plants growing in it to form roots and dried out due to the lack of water is easily picked up by wind eroding the soil. This can become a problem when lots of topsoil dries out to become dust which is picked up by the wind this
