Atmosphere Definition from Science & Technology Dictionaries & Glossaries
The gaseous or air portion of the physical environment that encircles a planet. In the case of the earth, it is held more or less near the surface by the earth's gravitational attraction. The divisions of the atmosphere include the troposphere, the stratosphere, the mesosphere, the ionosphere, and the exosphere.
Is the mixture of gases and water vapor surrounding the earth.
One atmosphere is 14.7 pounds per square inch (105 Newtons per square meter); the average atmospheric pressure at sea level on Earth.
Atmosphere Definition from Encyclopedia Dictionaries & Glossaries
An atmosphere (New Latin atmosphaera, created in the 17th century from Greek ἀτμός [atmos] "vapor" and σφαῖρα [sphaira] "sphere") is a layer of gases that may surround a material body of sufficient mass, and that is held in place by the gravity of the body. An atmosphere may be retained for a longer duration, if the gravity is high and the atmosphere's temperature is low. Some planets consist mainly of various gases, but only their outer layer is their atmosphere.

Atmosphere Definition from Sports Dictionaries & Glossaries
the blanket of air surrounding the earth, from sea level to outer space. Also, a unit of pressure; "one atmosphere" is pressure of the atmosphere at sea level, i.e., 760 mm Hg. Two atmospheres is twice this pressure, 1520 mm Hg, etc. Abbreviated atm.
Atmosphere Definition from Society & Culture Dictionaries & Glossaries
The mixture of gases surrounding the Earth. The Earth's atmosphere consists of about 79.1% nitrogen (by volume), 20.9% oxygen, 0.036% carbon dioxide and trace amounts of other gases. The atmosphere can be divided into a number of layers according to its mixing or chemical characteristics, generally determined by its thermal properties (temperature). The layer nearest the Earth is the troposphere, which reaches up to an altitude of about 8 km (about 5 miles) in the polar regions and up to 17 km (nearly 11 miles) above the equator. The stratosphere, which reaches to an altitude of about 50 km (31 miles) lies atop the troposphere. The mesosphere which extends up to 80-90 km is atop the stratosphere, and finally, the thermosphere, or ionosphere, gradually diminishes and forms a fuzzy border with outer space. There is relatively little mixing of gases between layers.

The gaseous layer covering the earth. The regions of the atmosphere are the Troposphere, Stratosphere, Mesosphere, Chemosphere, and the Thermosphere (which overlaps the Ionosphere and the Exosphere). The atmosphere is one of the four components, together with the Lithosphere, Hydrosphere, and Biosphere, that comprise the earth's ecosystem. Also see Air.

Atmosphere Definition from Religion & Spirituality Dictionaries & Glossaries
Atmosphere Any of various aery spheres enveloping a globe. On earth the lowest is familiar air, but there are others in the ethereal realms beyond, and the word is applied to mahat and manas, as mythologically represented by Indra, god of the firmament, the personified atmosphere (SD 2:614). However, mahat and its ray in the human being, manas, are far beyond in quality and ethereality anything that the human imagination understands by atmosphere -- unless it is endowed with the mystical sense that spiritus had among the philosophic ancients.
The elements of our present atmosphere are compounded from simpler elements which existed on earth at earlier stages of its evolution, and which exist now on some other globes. The atmosphere of our earth has become not only a chemical, but an alchemical crucible, in which "there is a perpetual exchange taking place in space of molecules, or atoms rather, correlating, and thus changing their combining equivalents on every planet" (SD 1:142). Neither sun nor stars are said to have our terrestrial elements, except in the sun's outer robes, for it is only in its outer robes that the integration of atomic substances become sufficiently physical to permit the appearance of our terrestrial elements; also our globe is said to have its own special laboratory on the far outskirts of the atmosphere, and when the atoms and molecules cross this, they change and differentiate from their primordial nature. The spectroscope may show certain similarities between the elements on sun and stars and those on earth but we have no logical right to infer identity in other respects; and actually the physical and chemical properties of atoms differ on different globes, as do also most of the effects of temperature (SD 1:142).
