a large part of the Japanese islands. Since sand is a basic element in all construction projects, and most often available in mixtures (gravel), there are numerous ideas being developed to remove the sand from mixtures. Depending on the size of the net that is used, this process sieves the sand into its size. Usually, this smooth sand
Generally, sand and gravel consist of an unconsolidated accumulation of rounded or semi-rounded rock fragments that result from the natural disintegration of rock (see entry on Weathering ). Sand and gravel can be described in terms of texture and composition. Texture refers to the size of grains, size sorting, and shape of grains.
Mining of sand and gravel on agricultural land is one of the alternative livelihood activities of the rural people in Nigeria which is now becoming an environmental issue.
