Soil formation is influenced by several factors including climate, topography, biological activity, and the underlying parent rock. The speed of soil formation increases in warmer climates with more biological and chemical activity. Sloping landscapes result in thinner soils than flat areas. Over long periods of time, ranging from hundreds to thousands of years, the weathering of rocks and decay of organic matter creates distinct soil layers and types tailored to the local environment. In India, the major soil types include forest and mountain soils, alluvial soils, red and yellow soils, black soils, laterite soils, and arid soils. Kerala soils consist of alluvial soils, laterite soils, forest soils, and red and black soils. Conservation
