Answer 1

definition: the envelope of gases surrounding the earth or another planet.

Question 2

Altitude

Answer 2

definition: the height of an object or point about sea level or ground level.
“flight data including airspeed and altitude”

Question 3

Density

Answer 3

definition: the degree of compactness of a substance

Question 4

Troposphere

Answer 4

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

Question 5

Troposphere

Answer 5

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

Question 6

Stratosphere

Answer 6

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

Question 7

Mesosphere

Answer 7

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.

Question 8

Thermosphere

Answer 8

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. An increase in temperature with height characterizes the thermosphere.

Question 9

Exosphere

Answer 9

definition: the outermost region of a planet’s atmosphere.

Question 10

Temperature

Answer 10

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

Question 11

Nitrogen

Answer 11

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.

Question 12

Carbon Dioxide

Answer 12

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.

Question 13

Oxygen

Answer 13

definition : a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.

Question 14

air pressure

Answer 14

definition: The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.

Question 15

concentration

Answer 15

definition: the action or power of focusing one’s attention or mental effort.

Question 16

condition

Answer 16

definition: the state of something with regard to its appearance, quality, or working order.

Question 17

constant

Answer 17

definition : occurring continuously over a period of time.

Question 18

continuous

Answer 18

definition : forming an unbroken whole; without interruption

Question 19

continuous

Answer 19
