what is weathering ?
how is soil formed?
Answers
Explanation:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. ... Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
______________
Parent materials
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

❥︎The soil is formed by weathering or disintegration of parent rocks by physical, chemical and biological agents. As a result of these processes, large rock pieces are converted into smaller pieces and eventually to soil. Living organisms such as lichens, insects, microorganisms make soil ready for the plants to grow.
