2. More living organisms live in soil than on it.
3. Sandy soil gets water logged easily.
4. Bedrock lies above the subsoil.​

Answer 1

Explanation:

5)Crop rotation helps to maintain soil structure and nutrient levels and to prevent soilborne pests from getting a foothold in the garden. When a single crop is planted in the same place every year, the soil structure slowly deteriorates as the same nutrients are used time and time again.

6)C-horizon

7)Porous loamy soils are the richest of all, laced with organic matter which retains water and provides the nutrients needed by crops. Sand and clay soils tend to have less organic matter and have drainage problems: sand is very porous and clay is impermeable.

true or false:

1)Soil minerals form the basis of soil. ... thunderstorms helps in the formation of soil but there are other elements too which help in formation of soil.

2)Soil is a living, dynamic resource. It helps grow food, fiber, and fuel. However, none of these processes can truly be carried out without the help of animals. For example, gophers, turtles, burrowing animals, and insects all live in the soil.

3)False. Water logging occurs in clayey soil, which absorbs and retains a lot of water. Sandy soil cannot absorb much water because of the large spaces between the soil particles.

4)A-Horizon, which contains humus, is the most fertile part of the soil. Bedrock lies beneath the subsoil.
