This is one of the earliest soil classification systems and was developed by the US Bureau of Soils in 1895 Fig As per this classification soils that have a particle size > 2 mm are called gravels those that have a particle size of 1—2 mm are called fine gravels those that have a particle size of —1 mm are called sands those that have a particle size of mm are
