OBJECTIVE FORESTRY

Detailed explanation-1: -Soil is formed by the breaking down of rocks by the action of wind, water and climate. This process is called weathering. The nature of any soil depends upon the rocks from which it has been formed and the type of vegetation that grows in it.

Detailed explanation-2: -Soil forms through the mechanical and chemical weathering of rocks and sediments, and the accumulation and decay of organic matter. The factors that affect the nature of soil and the rate of its formation include: Climate, especially average temperature and precipitation amounts, and the consequent types of vegetation.

Detailed explanation-3: -The formation of clastic and organic rocks begins with the weathering, or breaking down, of the exposed rock into small fragments. Through the process of erosion, these fragments are removed from their source and transported by wind, water, ice, or biological activity to a new location.

Detailed explanation-4: -Rocks which are acted upon by the forces of nature like water, wind, and the heat of the Sun, disintegrate into many pieces. This process is called weathering and it is the first step in soil formation.
