Humidity: the amount of moisture in the air

21
Q

Monsoon

A

Monsoon: a seasonal change in the direction of the prevailing wind

22
Q

Ocean currents

A

Ocean currents: the steady flow of surface ocean water in a prevailing direction

23
Q

Precipitation

A

24
Q

Prevailing winds:

A

Prevailing winds: winds that usually blow in one direction in one region

25
Q

Seasonal winds

A

26
Q

Wind direction

A

Wind direction: the direction from which a wind originates

27
Q

Wind speed:

A

Wind speed: a measure of the motion of air with respect to Earth’s surface

28
Q

Condensation

A

Condensation: occurs when water vapor in the air gets cold and changes back into liquid, which forms clouds

29
Q

Evaporation

A

Evaporation: occurs when the sun heats up water on Earth and turns it into vapor, which rises into the air

30
Q

Transpiration

A

Transpiration: occurs when plants lose water out of their leaves, and it is absorbed into the atmosphere

31
Q

Water cycle

A

Water cycle: a process that continually moves water from the ground to the atmosphere

32
Q

Chlorofluorocarbons

A

Chlorofluorocarbons: human-made gases that contain a combination of chlorine, fluorine, and carbon

33
Q

Carbon footprint:

A

Carbon footprint: the amount of carbon released into the air as a result of a human’s energy needs

34
Q

Exosphere

A

Exosphere: the outermost layer of the atmosphere

35
Q

Desertification

A

Desertification: the process by which fertile land becomes desert, typically as a result of drought

36
Q

Global warming

A

Global warming: the increase in Earth’s average surface temperature due to rising levels of greenhouse gases

37
Q

Greenhouse gases:

A

Greenhouse gases: the water vapor, carbon dioxide, and methane in the atmosphere

A

Ozone: a form of oxygen that has three oxygen atoms in each molecule

42
Q

Ozone layer

A

Ozone layer: a layer in the stratosphere that absorbs most of the ultraviolet radiation from the sun

43
Q

Pollutant

A

Pollutant: a substance that contaminates something, especially water or the atmosphere
