what is atmospheric

A thick gaseous envelope surrounding the earth is called atmosphere. The density of air in the atmosphere varies with altitude. Atmosphere is divided into five different layers or zones: Troposphere Stratosphere Mesosphere Ionosphere Exosphe..

This is a blanket of gaseous layer around the Eart..

Air is pulled towards the surface by gravity and this exerts pressure on the Earth's surface. The pressure exerted by the gases of the atmosphere on the surface of the Earth is called atmospheric pressur..

Lower the atmospheric pressure, higher is the rate of transpiration. Water Movement through the leaf to the atmosphere in the form of vap..

The atmosphere around earth is a blessing of nature on earth to have permitted the existence of life on it. Earth is endowed with an excellent resource of atmosphere - both to shield it from sun's harsh rays and other ill effects of celestial bodies as well as to provide t..

Atmospheric Pollutants - Many of the air pollutants are naturally present in the atmosphere in low concentration. They become pollutants when their concentration is relatively high. For example, SO 2 is considered as pollutant when its concentration in the atmosphere e..

Many of the air pollutants are naturally present in the atmosphere in low concentration. They become pollutants when their concentration is relatively high. For example, SO 2 is considered as pollutant when its concentration in the atmosphere exceeds the normal limit of 2 x 10 -..

Atmospheric Refraction - Atmospheric refraction is the shift in apparent direction of a celestial object caused by the refraction of light rays as they pass through Earths atmosphere. The twinkling of stars and variation in size of the Sun are due to atmospheric..

The atmospheric temperature governs the type of biodiversity, fertility of soil, the hydrological cycle and many other abiotic and biotic parameters of our planet. It acts as a resource - in the sense that optimum temperature promotes the production and productivity of many natural resou..

The atmosphere is the layer of air around the earth. It extends up to 1000 km above the surface of the earth and has a total weight of 4.5 10 18 kg (i.e., five million billion tons..
