The main component of air are oxygen and they will only react together at a normal temperature. For the formation of oxides of nitrogen, a very high temperature is required. 

In monsoon there is lot of humidity in air as compared to summer. Hence, the Clothes dry faster in summer than in monsoon

Warm air is lighter than cold air because they have more heat energy, which results in the increase in distances between the molecules. This decraeses the density, and hence makes it lighter than cold air.

Sea and land breezes are caused because of an uneven heating of the earth and through convection currents.

Dew are tiny drops of water that form on cool surfaces at night, when atmospheric vapour condenses.

Nitrogen is the major constituent of air. 

Argon is the most abundant and most used of the noble gases. Its chief uses are in metallurgy, where it provides an inert atmosphere in which hot metals can be worked. Because argon is so very unreactive, it prevents chemical reactions of the very hot metal being welded or forged.

Nitrogen constitutes nearly 78% of the atmosphere.
