1.	Explain the characteristic! of the various spheres of the Earth.
Answer» Earth is the most suitable planet to support life. It has three major components that we call as the realms of the Earth lithosphere, hydrosphere and atmosphere. (i) Lithosphere : The word lithosphere is derived from the Greek word Lithos, which means rocky. The Lithosphere is the land on which we live. (ii) Hydrosphere : The word Hydro means water in Greek. The hydrosphere consists of water bodies such as oceans, seas, rivers, lakes, ice caps on mountains and water vapour in the atmosphere. (iii) Atmosphere : The word Atmo means air in Greek. Atmosphere is the envelope of air that surrounds the Earth. Different types of gases make up the atmosphere. The major gases are Nitrogen (78%) and Oxygen (21%). (iv) Biosphere : The narrow belt of interaction among the lithosphere, the hydrosphere and the atmosphere, where life exists is known as Biosphere. Bio means life in Greek. It consists of distinct zones.
