Soil takes over a thousand years to form just one inch as it is created through the weathering of rocks and decomposition of organic matter. The key factors that influence soil formation are the parent rock, climate, topography, plants and animals, and time. Different soil types are found in various regions of India and around the world due to variations in these factors, especially topography and climate. Soil has important uses for construction, agriculture, and making bricks.
