Yes Rahul ,In Earth there is life..which contains oxygen,water.....

Anjali..Do you know what make our earth different from other planets?

Yes .Water has a great role in sustaining life and also for different purposes in day to day life ..

Temporary hardness The hardness of water containing calcium /magnesium bicarbonates is removed during boiling

Permanent hardness The hardness of water containing the chlorides and sulphates of calcium and magnesium is not removed even after boiling

Gases like oxygen and carbon dioxide dissolves in water

How are we surviving in this cold climate is there any magic behind it?

Its due to the Anomalous expansion of Water....
