Soil – The hard parenting rock undergoes weathering and produces unconsolidated granular particles of varying sizes , such formation is known as Soil.
Classification of soil- The soil is classified using most simplest geological classification. In this soil is classified in two categories
1. Residual soil – The soils which are resting on its parent rock without ant transportation, is termed as residual soils. These soils does not have any stratification, but it shows well distinguished soil profile. Example. Red soil, Black soil
2. Transported soils-The soils which are transported and get deposited in depressions on ground, is known as transported soils. Due to high velocity winds or water flow, loose soil particles transported along with organic and inorganic impurities. finally deposition of soil gives variety of transported soils. Example. Colluvial soils , Alluvial soils, Glacial soils, Eolian soils.
