What soil horizon forms last?
The O horizon is the topmost layer of soil that forms last. It consists of organic matter in various stages of decomposition, such as fallen leaves and plant material.
In soils with distinct soil horizons the topmost zone is?
The topmost zone in soils with distinct horizons is called the O horizon, also known as the organic horizon. It is composed mainly of organic materials such as decomposing leaves and plant matter.
Where is the O Horizon located?
The O Horizon, also known as the organic horizon, is the topmost layer of soil in a forest or woodland ecosystem. It is made up of organic matter such as fallen leaves, twigs, and other plant debris that is in the process of decomposing.
What IS AN O HORIZON?
The O horizon is the topmost layer of soil made up of organic matter in various stages of decomposition, like fallen leaves and twigs. It is commonly referred to as the litter layer and plays a crucial role in nutrient cycling and soil enrichment.
What types of materials make up the o horizon?
The O horizon, also known as the organic horizon, is composed of organic materials such as decomposing plant litter (leaves, twigs), animal remains, and living organisms like insects and microorganisms. It is the topmost layer of the soil profile and plays a critical role in nutrient cycling and soil fertility.

In soils with distinct soil horizons the topmost zone is?
The topmost zone in soils with distinct horizons is called the O horizon, also known as the organic horizon. It is composed mainly of organic materials such as decomposing leaves and plant matter.
Is soil dead or alive?
Both. Soil is divided by horizons. the topmost horizon if full of life. but then the B and C horizon. the C horizon is the bedrock and the B horizon is only clays and other minerals needed for plants to grow. But if the soil is eroded away over centuries then the soil in dead. hope this helps

What is the top most layer of soil?
The topmost layer of soil is called the O horizon or organic matter layer. This layer is primarily composed of decaying plant and animal material, providing nutrients to support plant growth.
What are the 4 horizons of soil profile?
The four horizons of a soil profile are O (organic), A (topsoil), B (subsoil), and C (parent material). The organic horizon is the topmost layer containing decomposed organic matter. The A horizon is rich in organic material and nutrients. The B horizon is a transition zone where leaching may occur. The C horizon is the lowest layer, consisting of weathered rock fragments.
Which horizon of soil is the parent soil?
THe c horizon
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)
What is topmost layer of soil called?
The topmost layer of soil is called the topsoil. It is rich in organic matter and nutrients, making it essential for plant growth.
Name All the horizons of a soil?
The horizons of a soil profile are O horizon (organic matter), A horizon (topsoil with organic material), E horizon (zone of leaching), B horizon (subsoil with accumulation of minerals), C horizon (weathered parent material), and R horizon (bedrock).
