The A horizon in soil is typically made up of mineral and organic material. In some instances the A horizon is only 2 to 3 inches deep, although it can be much deeper if the land has been plowed.
Partially weathered parent material is found in the C horizon of a soil profile.
The A horizon, the uppermost layer in the soil profile, often is called the surface soil. It is the part of the soil in which life is most abundant in such forms as plant roots, bacteria, fungi, and small animals. It is the part in which organic matter is most abundant. The B horizon lies immediately beneath the A horizon and often is called the subsoil. Lying between the A and C horizons, it utilizes the properties of both. Living organisms are fewer than in the A horizon but more abundant than in the C horizon. THE C horizon is the deepest of the three major horizons. It consists of the loose and partly decayed rock beneath the A and B horizons. The rock material in the C horizon is of the same kind which now forms the bulk of the soil above it.
The middle mantle, also known as the transition zone, is composed of dense silicate minerals such as bridgmanite, ringwoodite, and perovskite. These minerals can withstand high pressure and temperatures found in this region of Earth's mantle.
At 0 degrees Celsius, precipitation can fall as snow, sleet, or freezing rain depending on factors like atmospheric conditions and the temperature profile in the atmosphere.
This type of soil is known as loam soil. It is a balanced combination of sand, silt, clay, and organic material, making it ideal for gardening and agriculture due to its good water retention and drainage properties.

Partially weathered parent material is found in the C horizon of a soil profile.
The C horizon is based on bedrock. No soil is present that means that it is a layer of no penetration and usually consists of solid rock foundation.

Chrysotile is a form of asbestos accounting for about 95 percent found in the United States. It is a soft, fibrous silicate material. Chrysotile and other forms of asbestos are considered to be hazardous.
