Evaporation of surface water into vapors from Conduction from the ground
What does less dense air do when surrounded by more dense things
Sinks
Mixes with surrounding air
Rises
spirals onto a tornado
Air pressure at a location is related to...

Mass of air molecules
Total weight of air above it
amount of clouds in the air
what is a front, choose the best answer
The difference between low and high pressure air
The line between hot and cold air
The area where air masses mix
the boundary where different, large air masses meet
how do air masses move to create wind near earths surface? check all that apply
When low pressure air pushes into the space of high pressure air
When high pressure air pushes into the space of low pressure air
When more dense air slides underneath less dense air pushing it upward
When less dense air slides underneath more dense air pushing it upward
Intensity of sun light varies depending on what? Check all that apply
How far from equator you are
How long the light shine on a place
Longitudinal location
Angle the light hits an object
As warm air rises...
It gets closer to the sun and heats up
It transfers thermal energy to the surrounding air and cools
It gains thermal energy from the surrounding air and warms
none of the above
What explains why temperatures vary in the same pattern
moon phases
air mass movement (convection)
sun light intensity differences
none of the above
what causes seasons and variation in north and south hemisphere seasons
earth is tilted on it's axis
the earths orbit about the sun is very elliptical
the moon phases
all of the above
What conditions affect weather.
temperature
clouds
wind created by air mass movement
all of the above
What two things affect how much solar energy is transferred to thermal energy in the air
clouds
ground conduction
surface water
air pressure
What happens to molecules when heated, check all that apply
molecules in an object speed up moving fast and collide with other molecules transferring energy (conduction)
air molecules spread apart and become less dense
air molecules become more dense
air molecules create higher pressure
What happens to air molecules as they cool, check all that apply
air molecules slow down
air molecules become less dense
air molecules sink
air molecules move closer together
What process can move air masses in the atmosphere
conduction due to energy transfer through collision of molecules
convection due to different temperature and density of air
all of the above
none of the above
rising air pressure usually brings
clouds
rain
sun and clear skies
snow
cloudy skies occur when
there is low air pressure
there is high air pressure
when it is hot outside
when it is cold outside
which are true about air masses
warm air mass (less dense) will rise over a cold air mass (more dense)
air masses of similar temperatures will mix
A front (boundary between different air masses) will cause air masses to mix
All of the above
How do storm clouds form
they start with higher clouds that move down and flatten below
they start with low clouds that move up and push clouds above them higher, flattening at top
What causes storm clouds to form?
evaporation of surface water from ground conduction
low air pressure allows water vapor to rise
water vapor cools as it rises and condenses on particles in the air
all of the above
Where does rain usually occur?
Low-pressure areas where air is warmer, less dense and contain more water vapor
low pressure areas where air is cooler and denser
high pressure areas where air is warmer, less dense and contain more water vapor
high pressure areas where air is cooler, denser with less clouds
Climate is the average conditions over what period of time?
5 years
10 years
30 years
50 years
Average yearly temperature varies by what?
latitude
city
longitude
season
Which are true about sunlight (thus thermal) intensity differences in different areas on earth. Check all that apply
Shape of earth and axial tilt causes light to be more spread out at poles
sun hits more directly with more intensity at the equator
more direct and intense sunlight means colder temperaures
The equator has more variation in temperature then the different hemispheres
