The layer that would be located farthest from the surface of the Earth in a temperate region is bedrock (R).
The soil layers in a temperate region are typically arranged in a specific order, with each layer having distinct characteristics. To determine which layer would be located farthest from the surface of the Earth, we need to understand the order of these layers.
The first layer is the topsoil (A), which is the uppermost layer of soil. It is rich in nutrients and organic matter and is where most of the plant roots are found.
Below the topsoil is the parent material (C), which is the layer that gradually forms into soil through weathering processes. It consists of broken down rocks and minerals.
Next is the organic layer (O), which is made up of decomposed plant and animal matter. This layer is commonly found in forested areas and contributes to the fertility of the soil.
Finally, the layer located farthest from the surface of the Earth is the bedrock (R). It is a solid and unweathered layer of rock that underlies all other soil layers. Bedrock serves as the foundation for the entire soil profile.
Therefore, in the given list, the layer farthest from the surface of the Earth would be the bedrock (R).

It uses a lot of Earth’s energy.
The correct answer is: It takes so long to form.
Soil is considered to be a nonrenewable natural resource because it takes a very long time to form. It is the result of weathering processes that break down rocks and minerals over hundreds or thousands of years. Once soil is depleted, it takes a significant amount of time to regenerate, making it nonrenewable on human timescales.
