Q

aneroid barometer what is it made out of

A

consists of an airtight metal chamber

19
Q

units of air pressure

A

inches of mercury (inches for the public), millibars

20
Q

Altitude

A

the distance above sea level (air pressure decreases as altitude increases)

21
Q

High pressure

A

cold, dry air rushing down to Earth’s surface

22
Q

Low pressure

A

hot air rising into the atmosphere, creating clouds

23
Q

Convection

A

heat transfer by the motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it

24
Q

Conduction

A

Conduction is when heat energy is transmitted through touching

25
Q

Radiation

A

The transfer of energy through rays, for example from the sun (electromagnetic waves going down to earth)

26
Q

the green house effect

A

When the majority of the infrared radiation doesn’t travel into space and gets absorbed by vapor and carbon dioxide, and methane, and other gases. The energy from the absorbed radiation heats the gases in the air (these gases turn in hold heat in the earth’s atmosphere)

27
Q

wind

A

the movement of air parallel to earth’s surface (winds move from areas of high pressure to areas of low pressure)

28
Q

electromagnetic waves

A

a form of energy that can move through a vacuum of space

29
Q

Visible light

A

all of the colors you see in a rainbow R.O.Y.G.B.I.V

30
Q

infrared radiation

A

has wavelengths that are no longer wave lengths for red light

31
Q

ultraviolet radiation

A

wavelengths that are shorter then wavelengths for violet light

32
Q

Scattering

A

when dust size particles in the atmosphere disperse light in all directions

33
Q

Temperature

A

the average amount of energy of motion of each particle of a substance

34
Q

Thermal energy

A

measures the total energy of motion in the particles of a substance

35
Q

thermometer

A

a device that measures temperature

36
Q

convection currents

A

the upward movement of cool air

37
Q

anemometer

A

an instrument for measuring wind speed

38
Q

windchill factor

A

the increased cooling that wind can cause is a windchill factor

39
Q

local winds

A

the unequal heating of earth’s surface within a small area

40
Q

sea breeze

A

a local wind that blows from an ocean or lake

41
Q

land breeze

A

the flow of air from land to a body of water

42
Q

Global winds

A

winds that blow steadily from specific directions over long distances

43
Q

Coriolis effect

A

the way earth’s rotation makes wind curve

44
Q

which gas forms less then 1 percent of the atmosphere but is still essential to life?

A

Carbon dioxide
