NPTEL :: Atmospheric Science - Introduction to Atmospheric ScienceThe atmosphere of Earth is the layer of gases , commonly known as air , that surrounds the planet Earth and is retained by Earth's gravity. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface , absorbing ultraviolet solar radiation , warming the surface through heat retention greenhouse effect , and reducing temperature extremes between day and night the diurnal temperature variation. By volume, dry air contains Air composition, temperature, and atmospheric pressure vary with altitude, and air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Earth's troposphere and in artificial atmospheres. The atmosphere has a mass of about 5. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space.

Within the five principal layers above, which can be used to calculate densities or to convert between mole fraction and mass fraction, several secondary layers may be distinguished by pddf properties:. The average molecular weight of dry a. Recommended for you! Elements of nature.This layer is completely cloudless and free of water vapor. Calendar seasons Winter Spring Summer Autumn. Albert the Great, described the spherical shape of rain which in effect produced the rainbow. Clipping is a handy way to collect important slides you want to go back to later.

Due to this higher gravity, atmosphere deforms slightly towards the sun while draining a bit more air from the poles. Glossaries Meteorology Climate change Tornado terms Tropical cyclone terms.
It can be thought of as. This study consists of physics, chemistry, and dynamics of the atmosphere.
