   • It saves it from the hostile setting of the location.
   • It absorbs most of the cosmic rays from location and a serious portion of the radiation from the sun.
   • It transmits solely here ultraviolet, visible, close to infrared (300 to 2500nm) and radio waves. (0.14 to forty m) whereas filtering out tissue-damaging ultra-violate waves below concerning three hundred nm.
   • The atmosphere consists of N and O. Besides, argon, CO2, and trace gases.
2. Hydrosphere
   • The Hydrosphere contains every kind of water resources oceans, seas, lakes, rivers, streams, reservoirs, polar ice caps, glaciers, and H2O.
   • Nature ninety-seven of the earth’s facility is within the oceans,
     About a pair of water resources is latched within the polar icecaps and glaciers.
   • Only concerning a hundred and twenty-fifth is obtainable as recent surface water-rivers, lakes streams, and H2O acceptable be used for human consumption and different uses.
3. Lithosphere:
   • The lithosphere is the outer mantle of the solid earth. It consists of minerals occurring within the earth’s crusts and also the soil e.g. minerals, organic matter, air, and water.
4. Biosphere:
   • The biosphere indicates the realm of living organisms and their interactions with the setting, viz atmosphere, layer, and geosphere.
