0, 273, freezing
At absolute zero, the temperature is __ and al molecular motion ___

The energy requires to change a substance from one phase to another is called
latent heat
radiation emitted by the sun is often referred to as ___ radiation, while radiation emitted by the earth is often referred to as ___radiation
shortwave, longwave
what is the main reason we have seasons on earth?
the tilt of the earth causes the sun to hit the surface at different angles throughout the years
the four main temperature controls are?
land and water distribution, ocean currents, elevation, and latitude
which of the following would cause relative humidity to decrease?
a. cooling the air
b. warming the air
c. taking away water vapor
d. none of the above
c. taking away water vapor
which of these is not a greenhouse gas?
a. water vapor
b. ozone
c. hydrogen
d. methane
c. hydrogen
atmospheric pressure is measure of the ___ of the atmosphere
weight
pressure is measured in the following units
millibars, inches of mercury, hectopascal
moist air is ___ than dry air
more buoyant
In the northern hemisphere, the earth is ____ to the sun during the winter as opposed to summer
closest
Low clouds
stratus
middle clouds
alto
high clouds
cirro
layers of the atmosphere from Lowest to highest
troposphere, stratosphere, mesosphere, thermosphere, and exosphere
The transfer of heat by mass movement of a fluid such as air is called
convection
transfer of heat by the touching objects is called
conduction
T/F tempeture decreases with height in the stratosphere
F
T/F a cloud that is classified as a high puffy clouds if called a cirrostratus cloud
F
T/F ozone is a greenhouse gas
T
T/F the wavelengths for visible radiation is between ultraviolet and infrared radiation
T
T/F density is the weight of the atmosphere over a given area
F
T/F the ozone layer is found in the stratosphere and absorbs the earths radiation
F
T/F water vapor is the most playful green-house gas
T
T/F a low cloud that is layered is called an altostratus cloud
F
T/F the sun emits long wave ultraviolet radiation
F
T/F temperature inversions occur when cold air gets trapped beneath warm air
T
How does the earth heat up?
Convection causes the air molecules right above the surface to heat up. this causes warm air rot mix in the atmosphere. radiation from that sun is what warms the ground
how does the earth cool off at night?
at night the cold air mixes with the warm air which causes the air to cool.
