Detailed explanation-1: -This contains more clay and less organic matter. Beneath this is a layer of rocks called bedrock. As the bedrock or parent material is broken down it becomes weathered into bits and pieces naturally by water, ice, wind, and plants. These bits and pieces of rock form a large part of our soil.
Detailed explanation-2: -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.
Detailed explanation-3: -Recent studies that considered deep regolith and rock samples provided evidence that the chemical composition of bedrock can impart a substantial influence on soil erosion processes, thereby influencing the amounts of water and nutrients retained by the regolith12, 13.
Detailed explanation-4: -Soils are made up of living and non-living things and have qualities that make them good to grow plants. Non-living things include decomposed organic matter (from things that were once alive), minerals, water, and air. Living things include bacteria, fungi, worms, and insects. Not all soils are the same.
Detailed explanation-5: -The subsoil or B horizon contains minerals that have been transported deeper by groundwater. Most of the clay in soil has also been washed down to this layer. The partially weathered bedrock or C horizon is composed of broken up bedrock on top of the solid bedrock (parent material).
