7.3.1-Tony Flashcards
Atmosphere
Definition:the envelope of gases surrounding the earth or another planet
Altitude
Definiton: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.
Thermosphere
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
Defintion: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
Definiton: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
Definiton:a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
Air pressure
Definition:
the force exerted by air, whether compressed or unconfined, on any surface in contact with it.
Concentration
Definition:the action or power of focusing one’s attention or mental effort.
Condition
Definition:the state of something with regard to its appearance, quality, or working order.
Constant
Defition:occurring continuously over a period of time
Continuous
Definition:forming an unbroken whole; without interruption.
Conposition
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
Defition: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.
