7.3.1/Zaivion Flashcards
Atmosphere
Definition:The envelope of gases surrounding the earth or another planet.
Altitude
Definition: The height of an object or point in relation to sea level or ground level.
Density
Definition: The degree of compactness of a substance.
Troposphere
Definition: The lowest region of the atmosphere, extending from the earth’s surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere
Definition: The layer of the earth’s atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth’s surface (the lower boundary of the mesosphere).
Mesophere
Definition: the region of the earth’s atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Themosphere
Definition: 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
Definition: the outermost region of a planet’s atmosphere.
Temperature
Definition: 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
Definition: 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
Definition: 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
Definition: a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
Altitude
Definition: the height of an object or point in relation to sea level or ground level.
Density
Definition: the degree of compactness of a substance.
Air pressure
Definition: the force exerted on a surface by the air above it as gravity pulls it to Earth.
Concentration
Definition: the action or power of focusing one’s attention or mental effort.
Condition
Definition: he state of something with regard to its appearance, quality, or working order.
Constant
Definition: occurring continuously over a period of time.
Continuous
Definition: forming an unbroken whole; without interruption.
Composition
Definition: the nature of something’s ingredients or constituents; the way in which a whole or mixture is made up.
Elevation
Definition: the action or fact of elevating or being elevated.
Generate
definition: cause (something, especially an emotion or situation) to arise or come about.
Hazard
Definition: a danger or risk.
increase
Definition: become or make greater in size, amount, intensity, or degree.
Influence
Definition: the capacity to have an effect on the character, development, or behavior of someone or something, or the effect itself.
Inhabitable
Definition: suitable to live in; habitable.
Instability
Definition: lack of stability; the state of being unstable.
Layer
Definition: a sheet, quantity, or thickness of material, typically one of several, covering a surface or body.
Moderate
Definition: average in amount, intensity, quality, or degree.
Monitor
Definition: an instrument or device used for observing, checking, or keeping a continuous record of a process or quantity.
Originate
Definition: have a specified beginning.
Pollutant
Definition: a substance that pollutes something, especially water or the atmosphere.
Property
Definition: a thing or things belonging to someone; possessions collectively.
Radiation
Definition: the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
Region
Definition: an area or division, especially part of a country or the world having definable characteristics but not always fixed boundaries.
Relative
Definition: considered in relation or in proportion to something else.
Solar
Definition: relating to or determined by the sun.
Stable
Definition: (of an object or structure) not likely to give way or overturn; firmly fixed.
Structure
Definition: the arrangement of and relations between the parts or elements of something complex.
Surface
Definition: the outside part or uppermost layer of something (often used when describing its texture, form, or extent).
Uninhabitable
Definition: (of a place) unsuitable for living in.
