Question

The sphere of living matter together with air water and soil on the surface of the earth is known as
A. Lithosphere
B. Biosphere
C. Hydrosphere
D. Atmosphere

Answer 1

Hint:The area above the surface of the earth, on the surface of the earth, and below the surface of the earth is divided into different virtual spheres according to the presence of air water, soil, pressure, temperature.

Complete solution:
1:- Lithosphere:- It is the outermost part of the earth’s surface it consists of the earth’s crust also the upper part of the mantle. Lithosphere has it’s lower base from the land surface as well as from oceans. The depth of the lithosphere sphere inside the earth’s surface is about 80-100 km, so it consists of rigid rocky material inside it. The temperature of the lithosphere is about 300-500 degrees celsius.
2:- Biosphere:- Biosphere is that part of earth surface also the atmosphere which provides all the favourable conditions for the growth of plants, animals and other living organisms.. It is the area of the earth where living organisms live including the presence of air, water and soil. The biosphere is made up of living biota and the nonliving abiotic factors.
3:- Hydrosphere:- Hydrosphere is known for the presence of water on the surface of the earth or inside the earth. Hydrosphere can be in any form of water that is liquid, ice, water vapor.
4:- Atmosphere:- Atmosphere is the bag of gases presents above the surface of the earth. It consists of all vital gases to support life.

Hence option B) is the correct answer.

Note: we can understand the biosphere from the example of a pond where both biotic and abiotic factors present to support life in it. The sphere which has air, water, and soil all in a proper manner is best suited for the growth of the living organisms.
