Question

how is soil formed?.. please answer with full explaination.

Answer 1

Soil is formed by undergoing three processes.For the very first the big rocks are broken down into the small pieces by wind,water and air.This is known as physical weathering.then the small pieces goes under the chemical weathering which involves hydrolisis,oxidation and reduction.And the last stage is done by the action of microbes and microrganisms.This is known as biological weathering.and in this way the soil is formed.

Answer 2

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.
