The top layer of soil, known as topsoil, is rich in organic matter and nutrients and is where most plant roots grow. The bottom layer, or subsoil, is typically denser and contains fewer organic materials and nutrients. Topsoil supports more plant and microbial life, while subsoil mainly serves as a foundation for vegetation.

What is the definition of soil profile?
A soil profile is a vertical section of soil layers that shows the different horizons (layers) from the surface down to the parent material. It provides information about the composition, structure, and characteristics of the soil at a particular location.
What are the 6 layers of soil from top to bottom?
The 6 layers of soil from top to bottom are: 1. Organic layer (O horizon) - decomposing plant matter, 2. Topsoil (A horizon) - mixture of minerals, organic matter, and living organisms, 3. Eluviated layer (E horizon) - leached of minerals and clay, 4. Subsoil (B horizon) - accumulation of minerals and clay, 5. Parent material (C horizon) - partially weathered rock, and 6. Bedrock (R horizon) - unweathered rock.
What are the individual layers of soil?
The individual layers of soil, from top to bottom, are the O horizon (organic matter), A horizon (topsoil), B horizon (subsoil), C horizon (weathered parent material), and bedrock. Each layer has distinct characteristics and composition that influence soil fertility and productivity.
Where are the oldest layers of sediments located?
The oldest layers of sediments are typically found at the bottom of a sedimentary rock sequence, with the youngest layers at the top. Over time, new layers of sediments accumulate on top of older layers, creating a chronological sequence with the oldest layers at the bottom.
In sedimentation what order does the layers goes?
In sedimentation, the layers are arranged in chronological order with the oldest layer at the bottom and the youngest layer at the top. This is known as the Law of Superposition in geology, which helps scientists determine the relative ages of different rock layers.
What are the layers of soil from top to bottom?
The layers of soil from the bottom, or the deepest, layer to top are
What are the layers of soil from to to bottom?
The layers of soil from the bottom, or the deepest, layer to top are
Why are there layers in a rainforest?
The different layers of the rainforest are ( from top to bottom) , Emergents, Canopy, understory and the forest floor! Hope that helps you! :-) xx

When studying a stack of rock layers the layers are usually toward the bottom and the layers are usually toward the top?
In a stack of rock layers, the oldest layers are usually found at the bottom, while the youngest layers are found at the top. This is due to the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks will be at the bottom and the youngest rocks at the top.
How are rock layers arranging the geologic column?
The oldest rocks (layers) are at the bottom. The youngestrocks (layers) are at the top
What are the three layers of soil but not humus?
all i know the three types of soil are top soil sub soil and bedrock
What happens when the top layers of a glacier move faster then the bottom layers?
you are so stupid
How do you get fish to swimin the middle of tank?
Different types of fish swim in different layers of the water. Top floaters, bottom dwellers and middle swimmers.
