H horizons or layers: These are layers of organic material. Organic material is defined by having a certain minimum content of soil organic carbon. In the WRB, this is 20% (by weight). The H horizon is formed from organic residues that are not incorporated into the mineral soil.

What horizon is formed first?
The apparent horizon is formed first in the evolution of a black hole. It represents the point from which no light can escape, defining the boundary of a black hole's event horizon.
How do the horizon A and horizon B form?
There are many things that horizon A and horizon B could form. These things include slopes and lines for example.
The lowest horizon of a residual soil that formed in place is composed primarily of?
The lowest horizon of a residual soil formed in place is typically composed primarily of weathered bedrock or parent material. This horizon is known as the C horizon and is where the unweathered rock material transitions into partially weathered material that has been broken down by physical, chemical, and biological processes over time.
What is the B horizon?
The B horizon is the layer of soil underneath the A horizon, which is under the O horizon. The B horizon contains minerals and sand grains as well as organic material. If you didn't get it when your teacher explained it, ask him/her aboput it. They are sure to explain better than I can!
What are the layers that the formation of soil produces called?
The layers formed by the process of soil formation are called soil horizons. These horizons are categorized based on their composition, texture, and other characteristics, such as organic matter content and color. The layers typically include the O horizon (organic material), A horizon (topsoil), E horizon (eluviated/leached), B horizon (subsoil), and C horizon (parent material).

Which soil layers comprimise soil layers?
Soil layers are called soil horizons. Typically, a soil includes an A horizon, a B horizon and a C horizon. In laymen's terms: A horizon = topsoil B horizon = subsoil C horizon = parent material (the stuff in which the soil formed)
How do you explain sub soil?
it is the deepest soil found and is below horizon a and b
The lowest horizon of a residual soil that formed in place is composed primarily of?

This horizon is known as the C horizon and is where the unweathered rock material transitions into partially weathered material that has been broken down by physical, chemical, and biological processes over time.
What soil horizon contains the greatest amount of material formed by biological activity?
The uppermost O horizon contains the greatest amount of material formed by biological activity, such as decaying organic matter like leaves and plant roots. This horizon is rich in organic material and microbial activity, contributing to soil fertility and nutrient cycling.
What is the B horizon?
The B horizon is the layer of soil underneath the A horizon, which is under the O horizon. The B horizon contains minerals and sand grains as well as organic material. If you didn't get it when your teacher explained it, ask him/her aboput it. They are sure to explain better than I can!
How do you explain how rainbows are formed?
by the rain
What do you call the instrument that measures the angles formed by the line of sight to the north star and the horizon?
Azimuth
What is an easy way to explain how mountains are formed?
An easy way to explain how mountains are formed is through geological activities. Most mountains are formed as a result of volcanic eruptions while others are formed through erosion and other activities.
How far is it to the horizon when you are standing on the top of mt Everest a height of 8.85 km and explain?
Around 338.64 km
What horizon is the deepest?
The deepest soil horizon is typically the C horizon, also known as the "parent material." This layer is composed of unweathered rock or partially weathered rock from which the upper layers of soil are formed. Below the C horizon lies the bedrock, which is not considered a soil layer but rather the solid rock underlying the soil profile.
