Question

Carbosphere comprises
(a) Atmosphere
(b) Lithosphere
(c) Hydrosphere
(d) All of the above

Answer 1

Hint: It is a part of the sphere of the earth which comprises all those substances that constitute carbon. These substances that are made up of carbon may include air, water, earth, land, etc. Almost all of the components are made up of carbon.

Complete step by step answer:
The carbosphere is the atmosphere that is made up of carbon. This layer is composed of all the layers of the earth’s sphere that includes the Atmosphere, Lithosphere, and Hydrosphere along with the biotic and the abiotic factors.

- The spheres of the earth are also known as ecospheres, which leads to the development of the natural environment by joining many subsystems including the ecosystem.
- The biospheres comprises mainly of four layers:
(a) Atmosphere: It is a set of layers that are composed of various gases and surround the earth and is kept in place due to the presence of gravity. The gases that are present in the atmosphere are nitrogen (78%), oxygen (21%), carbon dioxide (0.04%), and other gases.
(b) Lithosphere: It is the hard outermost layer of the earth having crust and mantle. The lithosphere has several tectonic plates which if disturbed then results in the earthquake. The lithosphere is divided into two parts: oceanic lithosphere (where the crust is the ocean) and continental lithosphere (having continental crust).
(c) Hydrosphere: It is the layer that consists of water and is found in the upper, lower, and on the surface of the earth. Water has been found since an earlier age and changes its shape. It later leads to the continental drift resulting in the formation of the ocean and land.
(d) Biosphere: It is the layer of the sphere which comprises various life forms along with the abiotic factors. It constitutes all the ecosystems that are present on the earth.
So, the correct answer is ‘All of the above’.

Note: In 1875, Geologist Eduard Suess coined the term ‘biosphere’. The term ‘ecosystem’ was introduced in 1935 by Sir Arthur Tansley. The abiotic factors are the nonliving factors that include oxygen, water, sunlight, temperature, soil, climate, etc. They affect living organisms and have a huge impact on them.
