Answer 2

По́чва — поверхностный слой литосферы Земли, обладающий плодородием и представляющий собой полифункциональнуюгетерогенную открытую четырёхфазную (твёрдая, жидкая, газообразная фазы и живые организмы) структурную систему, образовавшуюся в результате выветривания горных пород и жизнедеятельности организмов[1].

Answer 3

What is soil and what is it made of?

Soil is a complex mixture of minerals, organic matter, water, air, and living organisms that forms the upper layer of the Earth's surface. It is a vital component of the Earth's ecosystem and plays a crucial role in supporting plant growth and providing habitat for various organisms.

The composition of soil can vary depending on factors such as climate, parent material, topography, and time. However, the basic components of soil include:

1. Minerals: Soil contains various types of minerals, such as sand, silt, and clay. These minerals are derived from the weathering and breakdown of rocks over time. The proportions of these mineral particles determine the soil's texture, which influences its ability to retain water and nutrients.

2. Organic Matter: Organic matter in soil is made up of decomposed plant and animal material. It includes dead leaves, roots, microorganisms, and other organic substances. Organic matter contributes to soil fertility by improving its structure, water-holding capacity, and nutrient content.

3. Water: Soil acts as a reservoir for water, holding it in the pore spaces between soil particles. Water is essential for plant growth and is also important for various soil processes, such as nutrient transport and microbial activity.

4. Air: Soil contains air in the pore spaces between soil particles. The presence of air is crucial for the survival of soil organisms and for the exchange of gases, such as oxygen and carbon dioxide, between the soil and the atmosphere.

5. Living Organisms: Soil is teeming with life, including bacteria, fungi, insects, worms, and other organisms. These organisms play important roles in nutrient cycling, decomposition of organic matter, and soil structure formation.

It's important to note that the composition of soil can vary significantly depending on factors such as location, climate, and land use practices. Different types of soil have different characteristics and are suited for different purposes, such as agriculture, gardening, or construction.
