Atmosphere

Question 1

 Made up of three oxygen molecules and protects us from the sun’s harmful UV radiation.

Answer 1

Ozone

Question 2

Upper limit of the atmosphere where the atoms and molecules blend into space.

Answer 2

Exosphere

Question 3

The layer of the atmosphere just above the stratosphere and below the thermosphere. It is the coldest part of the atmosphere and meteors burn up in this layer.

Answer 3

Mesosphere

Question 4

The layer of the atmosphere just above the troposphere and below the mesosphere. There is a temperature inversion due to the ozone layer which absorbs most of the sun’s UV radiation.

Answer 4

Stratosphere

Question 5

The layer of the atmosphere above the mesosphere where temperatures are the highest in the atmosphere. The increasing temperature is due to the strong influence of solar activity.

Answer 5

Ionosphere

Question 6

The layer of the atmosphere that is nearest to the Earth’s surface. It is where most weather changes occur. It is the thinnest layer yet contains half of the Earth’s atmosphere.

Answer 6

Troposphere

Question 7

The envelope of gases surrounding the earth.

Answer 7

Atmosphere

Question 8

A colorless, odorless unreactive gas that forms about 78 percent of the earth’s atmosphere.

Answer 8

Nitrogen

Question 9

Forms about 21 percent of the earth’s atmosphere, and is the most abundant element in the earth’s crust.

Answer 9

Oxygen

Question 10

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.

Answer 10

Carbon dioxide

Question 11

The phenomenon whereby the earth’s atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane.

Answer 11

Greenhouse effect

Question 12

Water in the form of a gas.

Answer 12

Answer 20

78%

21%

Seven

Question 21

Considered a greenhouse gas.

Answer 21

Carbon dioxide

Question 22

Transfer of energy from higher temperature objects to lower temperature objects.

Answer 22

Heat

Question 23

The process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods.

Answer 23

Heat transfer

Question 24

Heat transfer by direct contact/TOUCH.

Answer 24

Conduction

Question 25

Heat transfer through air and water; warm goes up because it is less dense due to particles moving faster and spreading apart, and cold goes down because the particles slow down and move closer together making them more dense.

Answer 25

Convection

Question 29

The horizontal movement of air from an area of high pressure to an area of lower air pressure.

Answer 29

Wind

Question 30

Winds that travel long distances in steady, predictable patterns.

Answer 30

Global winds

Question 31

More dense, sinking air creates this at Earth’s surface.

Answer 31

High air pressure

Question 32

Rising air creates this at Earth’s surface.

Answer 32

Low air pressure

Question 33

The effect of Earth’s rotation on the direction of winds and currents.

Answer 33

Coriolis Effect

Question 34

What causes warm and cool air masses to form, leading to wind.

Answer 34

Unequal heating of Earth’s surface

Question 35
