వాతావరణం : (ఆంగ్లం : atmosphere) : ద్రవ్యరాశి కలిగిన ఒక శరీరం చుట్టూ వాయువులతో కూడిన పొరను వాతావరణం అంటారు.[1] ఈ శరీరానికి వున్న ఆకర్షణ శక్తి ఎక్కువగానూ, వత్తిడి తక్కువగానూ ఉన్న మూలంగా, వాతావరణ పొర ఆ శరీరానికి అంటిపెట్టుకొని వుంటుంది. కొన్ని గ్రహాలు తమ వాతావరణంలో అనేక వాయువులను కలిగివుంటాయి.
భూమిపై వాతావరణం
The Earth's atmosphere consists, from the ground up, of the troposphere (which includes the planetary boundary layer or peplosphere as lowest layer), stratosphere, mesosphere, thermosphere (which contains the ionosphere and exosphere) and also the magnetosphere. Each of the layers has a different lapse rate, defining the rate of change in temperature with height.
Three quarters of the atmosphere lies within the troposphere, and the depth of this layer varies between 17 km at the equator and 7 km at the poles. The ozone layer, which absorbs ultraviolet energy from the Sun, is located primarily in the stratosphere, at altitudes of 15 to 35 km. The Kármán line, located within the thermosphere at an altitude of 100 km, is commonly used to define the boundary between the Earth's atmosphere and outer space. However, the exosphere can extend from 500 up to 10,000 km above the surface, where it interacts with the planet's magnetosphere.

ప్రాముఖ్యత
From the perspective of the planetary geologist, the atmosphere is an evolutionary agent essential to the morphology of a planet. The wind transports dust and other particles which erodes the relief and leaves deposits (eolian processes). Frost and precipitations, which depend on the composition, also influence the relief. Climate changes can influence a planet's geological history. Conversely, studying surface of earth leads to an understanding of the atmosphere and climate of a planet - both its present state and its past.
For a meteorologist, the composition of the atmosphere determines the climate and its variations.
For a biologist, the composition is closely dependent on the appearance of the life and its evolution.
