SEA BREEZE
1) During the day,
land heats up
faster and the
warm air rises.
The cool air over
the water blows
toward the land.
LAND BREEZE
2) At night, the
water is warmer,
and the warm air
rises. The air over
land is cooler, so
wind blows from
the land to the
sea.
3) Land heats up or absorbs energy
faster and cools off faster than
water.
------------------------------------------4) Cool air usually blows inland during
the day and out to sea at night.
------------------------------------------5) Before sunrise, if you walk down to
the beach, the air over the water is
warmer than the air over the land
which results in a land breeze.
------------------------------------------6) At noon, if you walk down to the
beach, the air over the land is warmer
than the air over the water which
results in a sea breeze.
------------------------------------------7) What occurs in a convection current?
Warm air rises and cool air sinks.
8) Where does most of the water
vapor in the air come from? oceans
------------------------------------------9) What causes water to evaporate
into the air? heat from the sun
------------------------------------------10) Warm air expands and rises,
creating an area of low pressure; cold
air is denser and sinks creating an
area of high pressure.
------------------------------------------11) What causes wind?
Changes in air pressure causes air
to move.
------------------------------------------12) How does wind tend to move?
from high to low pressure
-------------------------------------------
13) What part of the Earth receives
the most energy? Equator
------------------------------------------14) What causes wind to travel
counter clockwise in the northern
hemisphere and clockwise in the
southern hemisphere? Coriolis Effect
and the rotation of the Earth
------------------------------------------15) Describe the behavior of warm
and cold air molecules.
WARM AIR
COLD AIR
* rises & expands *sinks & contracts
*less dense
*more dense

------------------------------------------16) What global wind system affects
weather in the state of Georgia?
prevailing westerlies
17) What wind system is located
between 30 degrees to 60 degrees
latitude (N & S)? prevailing
westerlies
------------------------------------------18) Where are the Doldrums located?
at the Equator ~ 0 degrees latitude
------------------------------------------19) Label the wind systems of the
globe below.
20) Illustrate and compare a cold and
a warm front.
WARM FRONT
COLD FRONT
*precipitation
*warmer temperatures
 severe weather
 cumulonimbus
clouds
 thunderstorms &
possible
tornadoes
 cooler
temperatures
------------------------------------------21) What type of front produces
thunderstorms? cold front
------------------------------------------22) Does severe weather develop over
areas of high or low pressure?
low pressure (warm, moist air)
------------------------------------------23) How are tornadoes and hurricanes
different?
TORNADOES
HURRICANES
*form over land
*form over water
*have a vortex at *have an eye at its
its center
center
-----------------------------------------------------24) What type of clouds creates
thunderstorms? cumulonimbus
------------------------------------------25) What is the source of energy for
a tropical cyclone? (A.K.A hurricane,
himacane) warm, moist air
------------------------------------------26) Illustrate, label, and explain the
parts of a hurricane.
eye
eye wall
calm center
thick dense clouds @ the
eye; strongest winds
spiral
spiral arms that move
rainbands
around the hurricane
------------------------------------------27) Why do hurricanes lose strength
over land? Land is too dry & doesn’t
provide the fuel they need.(warm,
moist air)
------------------------------------------28) Draw and label the parts of the
water cycle.
------------------------------------------29) Define the following processes.
evaporation sun heats liquid water &
turns it into a gas which
rises into the air
transpiration water vapor is released
through plants’ leaves
condensation water vapor cools &
turns back into a liquid
& makes clouds
precipitation rain, sleet, snow, h-a-i-l
accumulation runoff; water that
empties into the ocean
