Match the columns Column I Column II a. Earth i) Very hot b. Revolution ii) path along which the Earth goes around the Sun c. Rotation iii) round d. Orbit iv) 365 days e. Core v) day and night

Column I Column II Explanation a. Earth iii) round The Earth is round in shape and is made up of rocks, water, and gases. It is a planet in the solar system. b. Revolution iv) 365 days The movement of the Earth around the sun is called a revolution, and it takes 365 days to complete one revolution. c. Rotation v) day and night The spinning of the Earth around an imaginary axis is called rotation, and this takes 24 hours. The period of 24 hours consists of a day and a night. d. Orbit ii) path along which the Earth goes around the Sun The path of the Earth and other planets around the Sun is called an orbit. This is an imaginary path. e. Core i) very hot The core is made up of hot melted metals. The major metals are iron and nickel, which are found in the core.
