OBJECTIVE FORESTRY

Detailed explanation-1: -Soil formation begins with the physical and chemical breakdown of the earth’s rocks, caused by atmospheric agents. These processes, known as weathering, chip away rock fragments and thus modify its inherent physical and chemical characteristics.

Detailed explanation-2: -Soil is formed as rock breaks down due to weathering and mixes with other materials. Soil forms whenever bedrock breaks. Soil formation continues over long periods of time.

Detailed explanation-3: -Soils develop because of the weathering of materials on Earth’s surface, including the mechanical breakup of rocks, and the chemical weathering of minerals. Soil development is facilitated by the downward percolation of water.

Detailed explanation-4: -Bedrock is made up of igneous, sedimentary, or metamorphic rock, and it often serves as the parent material (the source of rock and mineral fragments) for regolith and soil.
