dirt.
Usually a mixture of sand and clay and what not. basically bits of microscopic rock fragments.
Broken down Rock
The main source of organic material in soil is decaying plant and animal matter. This organic material undergoes decomposition by microorganisms, releasing nutrients that are essential for plant growth. Additionally, organic material helps improve soil structure, water retention, and nutrient availability.
The two main components of soil are organic matter, such as decaying plant and animal material, and inorganic matter, such as minerals and rocks. These components provide essential nutrients and structure for plant growth.
The organic material in soil is humus.
Soil is a heterogeneous material
Plants...
The main source of organic matter in soil is decomposed material from dead plants, animals and the solid waste resulting from animal digestion. Insects and bacteria act on them breaking them down into smaller and smaller pieces that mix with the rest of the soil.
Soil parent material is the underlying geological material from which soil is formed. It can be organic material, such as decomposed plant matter, or inorganic material, such as rocks or sediments. The characteristics of the parent material influence the properties of the resulting soil.

Organic Layer - plant litter Surface Layer - mineral and organic mixture Subsoil - contains clay, iron, aluminium Substratum - parent material
The main material in most soil is mineral content, primarily derived from weathered rock. This mineral component is composed of particles like sand, silt, and clay, which provide structure and fertility. In addition to minerals, soil also contains organic matter, water, and air, all of which contribute to its overall composition and health. The balance of these components varies depending on the soil type and its environment.
The correct Answer is: Transported Soil
