Answer 1

Hint: Our planet earth revolves around the Sun. It is also known as the Blue planet because of the presence of water in it. It is the third planet from the Sun after Mercury and Venus.

Complete answer: Option a: The layer of gases which surrounds our earth is called the Atmosphere. Dry air contains 78.09 percent Nitrogen, 20.95 percent oxygen, 0.93 percent argon and 0.04 percent carbon. This domain of the earth does not consist of solid rocks. This is the incorrect answer.
Option b: The domain of earth which consists of all the water of earth is called the Hydrosphere. Hydrosphere also includes surface water of the planet, underground water and water in the air. All the forms of water which are liquid, vapour and ice are included in hydrosphere. This domain of the earth does not consist of solid rocks. This is the incorrect answer.
Option c: The rigid outermost shell of a planet is called the Lithosphere. The lithosphere of earth is composed of crust and solid rocks. The domain of the earth consisting of solid rocks is the lithosphere. This is the correct answer to this question.
Option d: None of these can not be the correct answer because the domain of the earth consisting of solid rocks is the lithosphere. This is the incorrect answer to this question.

Option c is the correct answer to this question because the domain of the earth consisting of solid rocks is the lithosphere.

Note: There are three major layers in the interior of our planet namely Crust, Mantle and Core. The crust and the upper mantle together form the lithosphere part of our planet earth.
