metamorphic rocks
If the layer is of dead plants, it is a compressed layer known as a coal seam.
The layer of soil that is made up of only partly weathered rock is called the C horizon, also known as the parent material layer. This layer is located below the B horizon and consists of partially weathered rock fragments that are not yet fully decomposed into soil.

A thin rocky outer layer is known as the: Crust
ozone layer
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.
The third layer of soil structure, known as the C horizon, typically consists of partially weathered parent material. This layer is where the weathered rock fragments accumulate, and it contains less organic matter and nutrients compared to the top layers. The C horizon is usually denser and harder due to the presence of relatively unaltered materials.

The layer of coal between rocks is called a coal seam or coal bed. This layer forms over millions of years from compressed plant material.
A layer of rock and mineral fragments produced by weathering is called sediment. Sediment is formed when rocks are broken down into smaller pieces by physical, chemical, or biological weathering processes, and then these fragments are transported and deposited by water, wind, or ice. Over time, these sediment layers can become compacted and cemented together to form sedimentary rocks.
Corticated ossific fragments are pieces of bone that are surrounded by a layer of cortical bone, making them more well-defined and easier to distinguish on imaging studies like X-rays or CT scans. These fragments are usually associated with fractures or injuries to bones.
The C horizon is the layer of a soil profile that forms first from the bedrock. It is the underlying layer that contains weathered rock fragments and shows the least amount of soil development.
Is a solid layer of rock lying beneath Earth's soil layer. Bedrock: Is the source of rock and mineral fragments that make up soil. Is not weathered if it is not exposed to wind and water.
application layer
Soil scientists divide soil into horizons based on depth and soil make up. The O horizon, the very top layer right under the grass, is where the top soil is. This is the soil that is critical to human life.
Troposphere The lowest layer of the atmosphere is known as the Troposphere. Weather occurs in this layer.
