The loose covering of weathered rock particles overlying bedrock is called regolith. It consists of a mix of soil, sand, gravel, and other particles that have been broken down over time through weathering processes.
If you are asking for the name of such soils, they are soils formed in residuum, or residual soils. Typically, the soil profile grades into a degraded bedrock called saprolite, with depth, before hiyting hard bedrock.
Bedrock can be weathered through physical processes such as freeze-thaw cycles, abrasion from wind and water, and biological activities like plant root growth. Chemical weathering can also occur, where rock minerals are broken down by reactions with water, oxygen, or acids. Over time, these processes can break down bedrock into smaller particles and contribute to the formation of soil.
The term you are looking for is "topsoil." Topsoil is the uppermost layer of soil, rich in organic matter and nutrients, where most of the plant roots grow. It is above the zone of partly weathered bedrock and is crucial for plant growth and productivity.
Weathered parent rock typically contains a mix of minerals and organic material. It may also include elements like clay, silt, sand, and other residual particles depending on the weathering process. These components are the result of physical, chemical, and biological breakdown of the original rock material.
The layer of soil that is partially weathered bedrock is known as the "C horizon" or the "parent material layer." It contains a mix of weathered rock fragments and soil particles, with limited organic matter compared to upper soil layers.
Weathered bedrock contributes to soil formation by breaking down into smaller particles through physical, chemical, and biological processes. This process exposes minerals and nutrients within the bedrock, allowing them to mix with organic matter to create fertile soil. Over time, this weathered material further decomposes and enriches the soil with essential elements for plant growth.

Weathered particles that become soil are known as parent material or bedrock. These particles are broken down through weathering processes such as erosion, deposition, and biological activity to form the basis of soil. Over time, these weathered particles mix with organic matter and minerals to create the fertile soil necessary for plant growth.
Organic matter, such as decaying plant and animal residue, combines with particles of weathered bedrock to make the fertile soil of the Midwest. This process helps provide essential nutrients for plant growth and contributes to the productivity of the region's agriculture.
It is false that the loose material on Earth's surface that contains weathered rock particles and humus is bedrock. The loose weathered material on Earth's surface in which plates can grow is soil.

Solid rock is being weathered at the bedrock layer, which is the deepest layer of the soil profile. Weathering processes like physical breakage and chemical decomposition act on the bedrock to gradually break it down into smaller particles, contributing to soil formation.
Clay, silt, and sand are the three types of weathered rock particles found in soil.
The process of solid rock being weathered into soil typically occurs in the parent material layer of the soil profile, which is the layer closest to the unaltered bedrock. Weathering processes, whether physical or chemical, gradually break down the solid rock into smaller particles to form the soil.
The layers of soil in an area are the topsoil, subsoil, weathered rock and bedrock.
Bedrock can be weathered through physical processes such as freeze-thaw cycles, abrasion from wind and water, and biological activities like plant root growth. Chemical weathering can also occur, where rock minerals are broken down by reactions with water, oxygen, or acids. Over time, these processes can break down bedrock into smaller particles and contribute to the formation of soil.
