(a) Weathering-The action of the elements of climate and weather, animals, and plants on the land surfaces to break them down biologically, chemically, and physically is called weathering.
(b) Soil erosion-Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.
(c) Soil pollution-Soil pollution refers to the contamination of soil with anomalous concentrations of toxic substances.
(d) Percolation-Percolation is the movement of water through soil, and the percolation rate is the speed at which that movement occurs.
