what is the different layers of soil?
437635
The main layers of the soil are topsoil, subsoil and the parent rock. Each layer has its own characteristics. These features of the layer of soil play a very important role in determining the use of the soil. Soil that has developed three layers, is mature soil.

Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly.

Most soils have three major horizons -- the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation).

Dirt is what you get under your fingernails, while soil is the thin living skin that covers the land. ... Organic matter (fallen leaves, dead plants, and animals) decays and mixes with inorganic material (rock particles, minerals, and water) to form soil. Soil can be divided into many layers also called HORIZONS.

The Inner and Outer Core, The Mantle, The Crust Earth has four different layers: the inner core, the outer core, the mantle, and the crust.

The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air.

Broadly speaking, the Earth has four layers: the solid crust on the outside, the mantle and the core — split between the outer core and the inner core.

The structure of the Earth is divided into layers. These layers are both physically and chemically different. The Earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid center called the inner core.

Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma.

There are six main types of soil: chalky, clay, loamy, peaty, sandy and silty. To test your soil, you need to take a look at it and feel it. Add water and try rolling it between your hands.

Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms. The relative influence of each factor varies from place to place, but the combination of all five factors normally determines the kind of soil developing in any given place.

There are three types of soil particles: sand, silt and clay. Most soils are made up of a combination of sand, silt and clay particles. The ratio of these particles in any given soil sample identifies it as one of the three main types of soil: sandy, loam or clay.

Soil is a complex matter and comprises minerals, soil organic matter, water, and air. These fractions greatly influence soil texture, structure, and porosity. These properties subsequently affect air and water movement in the soil layers, and thus the soil's ability to function.
