What are the 4 soil horizons?
The four soil horizons are O horizon (organic layer), A horizon (topsoil), B horizon (subsoil), and C horizon (parent material). These horizons make up the soil profile and each has distinct characteristics based on their composition and arrangement.
What are the vertical layers of soil called?
The vertical layers of soil are called soil horizons. These horizons are classified based on their composition, texture, color, and other characteristics, and they include the O horizon (organic matter), A horizon (topsoil), B horizon (subsoil), C horizon (parent material), and sometimes the R horizon (bedrock).
How many horizons are in a soil profile?
A soil profile typically has three main horizons: topsoil (A horizon), subsoil (B horizon), and parent material (C horizon). Each horizon has distinct characteristics based on factors like organic matter content, color, structure, and composition.
What are the five layers of soil?
The five layers of soil, starting from the surface and moving downward, are the O horizon (organic matter), A horizon (topsoil), E horizon (leached zone), B horizon (subsoil), and C horizon (parent material). These layers differ in their composition, structure, and nutrient content, impacting plant growth and water filtration.
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.
How is the soil composition in the A horizon related to the composition or the R horizon?
by the topsoil

What are Horizon lines in a photograh?
The horizon line in a photograph is where the sky meets the land or water. It is often used as a reference point for determining composition and balance in a photo. Placing the horizon line higher can emphasize the sky, while placing it lower can emphasize the foreground.
When using two point perspective in a composition the vanishing points are located?
The two vanishing points are placed apart on the same horizon line (horizontal eye line of viewer). The horizon is the first line to be drawn.
What transports material to the B horizon?
Water moving through the soil carries material from the A horizon to the B horizon through a process called leaching. This process can transport nutrients, minerals, and organic matter down through the soil profile, affecting the soil's fertility and composition.
What term for a layer of soil that differs in color and texture from the layer above and below it?
That would be a "soil horizon." Each horizon represents a different stage of soil development and can vary in color, texture, structure, and composition.
What is the Horizon Line in 2PP?
The horizon line in a two-point perspective drawing represents where the sky meets the ground or other elements in the scene. It is a horizontal line that helps to establish the viewer's eye level and vanishing points in the composition.
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).
