Atmosphere
The earth is surrounded by a layer of gas called the atmosphere.
- The atmosphere extends up to a height of about 1,600 kilometer’s.
2. The atmosphere is divided into five layers based on composition, temperature and other properties and they are:
1.The troposphere
2. The stratosphere
3. The mesosphere
4. The thermosphere
5. The exosphere
About 99 per cent of clean and dry air in the atmosphere is composed mainly of nitrogen and oxygen. Nitrogen 78 per cent, oxygen 21 per cent and other gases like carbon dioxide, argon and others comprise 1 per cent by volume.

The hydrosphere includes water on earth in Oceans, Seas, Rivers, Lakes and even in frozen forms.
Only 2.5% of Earths water is freshwater. And even in this 2.5%; approximately 69% is in the form of snow and ice.
97.5% of Earths water is salt water, which is unfit for human consumption.
Approximately 71% of the Earth surface is covered by oceans.
Oceans
The three chief movements of ocean waters are the waves, the tides and the ocean currents.
Oceans are the major part of the hydrosphere and they are all interconnected.
