Question 1Erosion is enhanced by the speed of the moving water and by reducing the amount of exposed surface, there is a reduction in the number of sediments transported downslope. Majorly, erosion is of four types which are as a result of direct rainfall: sheet, rill, splash and gully erosions. However, of the four processes, splash erosion is the initiator which is followed by sheet erosion while rill and gully follow it consecutively. It has been noted that the most severe of the erosion processes is the splash erosion which is caused by the raindrops falling on the bare surface. The raindrops have the kinetic energy to dislodge the soil particles from the matrix and therefore initiate the erosion process. Therefore a reduction in the amount of surface exposed to the rain results to a decrease in the amount of erosion.The experiment indicates that erosion for the slopes with gradients of 2%, 4%, 6%, 8% and 10% is higher on surfaces without cover than on the same surfaces with cover. However, the same is not true for the surfaces with slopes of 1%, 3%, 5%, 7% and 9%.The discrepancy has been rectified by the line of best fit.However,comparison may be observed on a bar graph.123456789100200400600800100012001400160018002000Chart Titleno cover with cover
