Atmosphere
the envelope of gases surrounding the earth or another planet.
Altitude
The height of an object or point in relation to sea level or ground level.
Density
The degree of a substance.
Troposphere
The lowest layer of earth’s atmosphere.
Stratosphere
The very highest level of a profession or other sphere.
Mesosphere
the part of the earth’s atmosphere between the stratosphere and the thermosphere in which temperature decreases with altitude to the atmosphere’s absolute minimum.
Thermosphere
the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Exosphere
the outermost region of a planet’s atmosphere.
Temperature
the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
Nitrogen
the chemical element of atomic number 7, a colorless, odorless unreactive gas that forms about 78 percent of the earth’s atmosphere. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant.
Carbon Dioxide
a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
Oxygen
a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
air pressure
another term for atmospheric pressure.
concentration
condition
the state of something with regard to its appearance, quality, or working order.
constant
occurring continuously over a period of time.
continuous
forming an unbroken whole; without interruption.
composition
the nature of something’s ingredients or constituents; the way in which a whole or mixture is made up.
elevation
the nature of something’s ingredients or constituents; the way in which a whole or mixture is made up.
generate
cause (something, especially an emotion or situation) to arise or come about.
hazard
chance; probability.
increase
become or make greater in size, amount, intensity, or degree.
Influence
the capacity to have an effect on the character, development, or behavior of someone or something, or the effect itself.
inhabitable
suitable to live in; habitable.
instability
lack of stability; the state of being unstable.
layer
a sheet, quantity, or thickness of material, typically one of several, covering a surface or body.
moderate
average in amount, intensity, quality, or degree.
monitor
an instrument or device used for observing, checking, or keeping a continuous record of a process or quantity.
originate
have a specified beginning.
pollutant
a substance that pollutes something, especially water or the atmosphere.
property
a thing or things belonging to someone; possessions collectively.
radiation
the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
region
an area or division, especially part of a country or the world having definable characteristics but not always fixed boundaries.
relative
considered in relation or in proportion to something else.
solar
relating to or determined by the sun.
stable
(of an object or structure) not likely to give way or overturn; firmly fixed.
structure
the arrangement of and relations between the parts or elements of something complex.
surface
the outside part or uppermost layer of something (often used when describing its texture, form, or extent).
uninhabitable
