20
Q

friction:

A

the opposing force, due to contact, that causes an object to slow down

21
Q

fronts:

A

the boundary between two differnt air masses. AND the area between the 2 air masses where temps and humidty change

22
Q

fronts almost always bring……….

A

precipitation! at the frontal surface warm air rising high into the troposphere means cooling

23
Q

cold front

A

cold air is advancing and displacing warmer air. weather is wet with heavy precipitation

24
Q

warm front

A

warm air is pushing ahead displacing colder air. warm temps follow the passage of the front

25
Q

stationary front

A

if neither are air mass is being displaces, temps remain stagnant, and winds are gentle to nil

26
Q

rain shadow:

A

an area of dry land on the leeward (or downwind) side of the mountain

27
Q

thunder storms

A

most often associated to the cumulonimbus cloud, cold front often create these, and they produce UNSTABLE enviornment

28
Q

thunder storm stage the cumulous stage 1

A

warm air rising and conditions to form clouds

29
Q

thunder storm stage the mature stage 2

A

strong updraft of warm, moist air, AND a strong downdraft of wind and precipitation

30
Q

thunder storm stage the dissipation stage 3

A

surface has cooled, cutting off the warm, moist air that “fuels” the storm

31
Q

lightning

A

created by friction between the rising updraft and the falling downdraft in a cumulonimbus cloud

32
Q

tornados

A

rotating column of air
related to supercells

33
Q

insolation

A

the incmoming solar radiation (energy from the sun) that reaches earth

34
Q

greenhouse effect

A

the process by which gasses absorb heat energy from the sun and prevent heat from leaving out atmosphere
good for warmth
bad for global warming

35
Q

primary greehouse gasses (3)

A

water vapor, carbon dioxide, and methane

36
Q

secondary greenhoue gasses (2)

A

nitrous oxide, and ozone

37
Q

global warming:

A

an increase in average global temperatures

38
Q

5 things that cause an increase in greenhouse gases

A

carbon dioxide
fossil fuels
deforestation
volcanoes/fires
methane

39
Q

3 main zones

A

tropical, tempature, and polar

40
Q

ocean currents

A

patterns of ocean waters that move in regular patterns heavily influence weather along coastal communities

41
Q

ways to protect earth

A

reduce global warming

42
Q

side effects of reducing global warming..

A

spread of disease
rising sea levels
melting glaciers

43
Q

renewable resources are..

A

a resource that can be replaced in nature–can be replenished over months

44
Q

nonrenewable resources are…

A

a resource that exists in a fixed amount that cannot be replaced by nature at the same rate it is used

45
Q

ore..

A

any rock that contains enough of a particular mineral

46
Q

reserve:

A

the known deposits of a mineral in ores that are worth mining.

47
Q

oil

A

liquid formed more than 300 million years ago from the remains of diatoms (ancient sea creatures) which convert sunlight directly into stored energy

48
Q

USA oil reseserves are where? (5)

A

california
Alaska
Texas
Oklahoma
Louisiana

49
Q

main ingredient in gas is..

A
