Answer 2

study of weather and how the atmosphere heats and cools

Question 3

climatology

Answer 3

study of earths long tern weather and how climate controls the climate and determines it in an area

Question 4

wind chill scale:

Answer 4

chart that converts the actual tempature outside to the temp the body would feel if exposed to the air and wind

Question 5

frostbite

Answer 5

frozen body tissue

Question 6

humidity:

Answer 6

amount of moisture in the atmosphere make hot temps hotter and cold temps colder

Question 7

transpiration

Answer 7

essentially evaporation of water from plant leaves

Question 8

air pressure

Answer 8

changes in air pressure, earspop etc

Question 9

how much of the atmosphere is nitrogen (%)

Answer 9

78%

Question 10

how much of the atmosphere is oxygen (%)

Answer 10

21%

Question 11

dew point

Answer 11

atmospheric temp below which water droplets begin to condense and dew is formed

Question 12

air pressure

Answer 12

weight of the air as it pushed down upon the earths surface

Question 13

which is heavier? dry air or wet air

Answer 13

dry air

Question 14

barometer:

Answer 14

an instrument to measure air pressure mercury and aneroid

Question 15

two ways air pressure is reported

Answer 15

mercury and millibar

Question 16

low pressure means…

Answer 16

the air is rising-warmer and more humid air.

Question 17

high pressure means…

Answer 17

air is falling- cooler and dryer air

Question 18

isobars:

Answer 18

a line that joins points having the same air pressure (remeber weather maps)

Question 19

Coriolis force:

Answer 19

the tendency of an object moving freely over the earths surface to curve away from its path of travel.

Question 20

friction:

Answer 20

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

Question 21

fronts:

Answer 21

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

Question 22

fronts almost always bring……….

Answer 22

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

Question 23

cold front

Answer 23

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

Question 24

warm front

Answer 24

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

Question 25

stationary front

Answer 25

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

Question 26

rain shadow:

Answer 26

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

Question 27

thunder storms

Answer 27

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

Question 28

thunder storm stage the cumulous stage 1

Answer 28

warm air rising and conditions to form clouds

Question 29

thunder storm stage the mature stage 2

Answer 29

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

Question 30

thunder storm stage the dissipation stage 3

Answer 30

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

Question 31

lightning

Answer 31

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

Question 32

tornados

Answer 32

rotating column of air related to supercells

Question 33

insolation

Answer 33

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

Question 34

greenhouse effect

Answer 34

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

Question 35

primary greehouse gasses (3)

Answer 35

water vapor, carbon dioxide, and methane

Question 36

secondary greenhoue gasses (2)

Answer 36

nitrous oxide, and ozone

Question 37

global warming:

Answer 37

an increase in average global temperatures

Question 38

5 things that cause an increase in greenhouse gases

Answer 38

carbon dioxide fossil fuels deforestation volcanoes/fires methane

Question 39

3 main zones

Answer 39

tropical, tempature, and polar

Question 40

ocean currents

Answer 40

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

Question 41

ways to protect earth

Answer 41

reduce global warming

Question 42

side effects of reducing global warming..

Answer 42

spread of disease rising sea levels melting glaciers

Question 43

renewable resources are..

Answer 43

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

Question 44

nonrenewable resources are...

Answer 44

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