Soil is the component of

evs mud and stones importance of soil in agriculture soil - formation, profile and properties soil as a natural resource

  1. Atmosphere

  2. Lithosphere

  3. Hydrosphere

  4. Exosphere

Show answer
Correct Option: B
Explanation:

The lithosphere is the solid portion of the Earth. It is a dense shell of material, that surrounds the entire planet. Even though most of the Earth's surface is covered with water, underneath, that water is a solid layer of rock. With the exception of ice, basically any solid non-organic material on the Earth is from the lithosphere. This includes soil, rocks, sand, etc.

Which of the following is the important natural resources for plants and animals?

evs mud and stones importance of soil in agriculture soil - formation, profile and properties soil as a natural resource

  1. Coal

  2. Petrol

  3. Diesel

  4. Soil

Show answer
Correct Option: D
Explanation:

Soil, as we know an important abiotic component of our environment. It provides nutrition and water to grow crops. They hold the roots of the trees and are extremely necessary for the proper growth of plants and trees. In the absence of proper nutrients in the soil, the plants and trees show nutritional deficiencies and retarded growth.

Apart from this, animals depend on plants for their survival and so they are dependant on soil for providing habitat and proper development of plants that they consume.
Coal, petroleum and natural gas are important fossil fuels that also from non-renewable resources that are used for various reasons like running automobiles, house gas cylinders etc.

They are remnants of dead plants and animals over a long period of time. So, they are not related to the growth of plants and animals.


Soil helps plants by

  1. Supplying them water and minerals.

  2. Supplying them air.

  3. Preparing food in their plants.

  4. Helping them move from one place to another.

Show answer
Correct Option: A
Explanation:

The roots of the plants are held firmly in the soil. Different types of soil have different texture and particles. They have different levels of minerals and nutrients embedded in them. Roots absorb water from the soil by the process of osmosis. Along with water, mineral nutrients also enter the soil.

So, we can say that option A "Supplying them water and minerals" is the correct answer.
