7.3.1-Jacob Flashcards
Atmosphere
the envelope of gases surrounding the earth
Altitude
the height of an object or point in relation to sea level
Density
the degree of compactness of a substance.
Troposphere,
miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere
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
Mesosphere
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
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
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.
altitude
the height of an object or point in relation to sea level or ground level.
density
the degree of compactness of a substance.
air pressure,
the force exerted on a surface by the air above it as gravity pulls it to Earth
concentration
the action or power of focusing one’s attention or mental effort.
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
elevation
the action or fact of elevating or being elevated.
generate
cause (something, especially an emotion or situation) to arise or come about.
hazard
any source of potential damage, harm or adverse health effects on something or someone
increase
become or make greater in size, amount, intensity, or degree.
