    Solution:

    The above statement is false.
    There are many causes of soil erosion, out of which the most important causes are; Rainfall and flooding; the Higher intensity of rainstorms is the leading cause of soil erosion. Agriculture; When agricultural fields replace natural vegetation, topsoil is exposed and can dry out. Grazing; continued overgrazing reduces soil organic matter inputs because less plant biomass is available as litter, reducing soil organic matter, nutrients, and biotic activity. Logging and mining; Mining, particularly gem mining, has been responsible for severe soil erosion and river siltation problems. Construction, Rivers and streams, Heavy winds, Loss of arable land etc.
    The corrected statement would be, “ There are several causes for soil erosion”.
