Soil is the uppermost layer of landmass of the Earth. It is a life supporting medium, in which plants can grow. It is soft and porous in nature and contains enough nutrients and water for the growth of plants.Most of the landmass of the Earth is not covered with soil.
Soil has been formed from the parent rock material over millions of years. This process by which soil formation takes place is called weathering. So, Weathering is a very slow and gradual process during which parent rock material breaks down into fine particles.
