What are types of soil according to formation?
Soil can be classified based on formation as residual soil, which forms in place from underlying rock; transported soil, which is moved by water, wind, or glaciers from its original location; and organic soil, which forms from the accumulation of organic materials like leaves and plant debris.
Which soil horizon forms last?
The O horizon forms last in the soil profile as it consists of organic material like decaying leaves and plant matter on the soil surface. It is considered the top layer of the soil profile and is constantly being replenished by new organic material entering the system.
What form of phosphorus is present in the soil?
Phosphorus in soil can be found in several forms, including inorganic forms (such as phosphate) and organic forms (such as phospholipids in living organisms or humic substances). The availability and mobility of phosphorus in soil is influenced by its form and interaction with soil particles.
What is organic matter that is broken down into soil called?
Organic matter that is broken down into soil is called humus. Humus is a dark, organic material that forms in soil from the decomposition of plant and animal matter. It helps improve soil structure, nutrient content, and water holding capacity.
How does the inorganic portion of soil form?
The inorganic portion of soil forms from rocks getting weathered by chemical and physical means to form soils.
What does soil forms in?
Soil forms from ground rocks and organic material like compost.
What is dark organic material that forms in soil?
Humus

how does soil forms from rocks?
Lichen dies and create organic material and soil ,which plants grow new soil anyways

Can granite turn into soil?
It can become a part of soil. Soil is a mixture of organic and mineral/rock components. Just about any rock type can contribute to the inorganic portion.

What is the dark organic material that forms in soil as plant and animal matter decays?
The dark organic material that forms in soil as plant and animal matter decays is called humus. Humus is rich in nutrients and helps improve soil structure, moisture retention, and microbial activity, making it essential for healthy and fertile soil.
What is the organic constituent of soil called?
Humus is what the organic constituent of soil is called. It's dark brown, fresh smelling, nutrient rich organic matter. It's formed from the break down of dead and decaying animal and plant matter, and from animal waste products, in the soil.
What happen to a large portion of the carbon when organic matter decompose?
When organic matter decomposes, a significant portion of the carbon is released into the atmosphere as carbon dioxide (CO2) through the process of respiration by decomposer organisms. Some of this carbon can also be converted into other forms such as methane (CH4) during anaerobic decomposition. However, a small proportion of carbon can be retained in the decomposing material as organic matter in the form of humus or stored in the soil.
