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.

Soil is a mixture of small particles of rocks and humus. Temperature variations due to radiation from the sun, rainwater winds and living organism influence the formation of soil from the rocks involving two processes :weathering and paedogenesis.

Breakdown of bigger rocks into small find particle is called weathering. It may occur due to Physical chemical or biological means under the influence of solar radiation rock it up an expert at night this rockschool doubt and contract Singh's all parts of rocks not expand and contract at the same rate cracks appear in the rocks and ultimately the large rocks breakdown into smaller pieces flow of water through or over the rocks made the cracks be the flowing water also has a eraser cases on the rocks on freezing the water expands in rock crevices and break the rocks. similarly strong winds continue to rub against hard Rocks and erode them growth of Lichens mosses and other plants also influence the formation of finding the rocks mobile which they are growing
