6. Meteorologists have been tracking a
storm as it moved across the southeast
Atlantic Ocean. Radars indicated the
storm had winds moving faster than
119 miles per hour. A warning was
issued that it would reach landfall in 24

Air Pressure
Clouds
1. Where is air pressure the highest or
greatest? At sea level
1. How do clouds form? When water vapor in
the air is cooled, it condenses, clumps together
around dust particles and form droplets of
water.
2. Where is air pressure the lowest? At higher
altitudes
2. A cloud that covers most of the sky. stratus
3. What changes air pressure? Height above
sea level or altitude, water vapor, volume of air,
temperature
4. Big air pressure changes over a short
distance create strong winds.
5. Small air pressure changes cause gentle
winds.
3. A cloud that is puffy and white. cumulus
4. A cloud made of ice crystals and is located
high in the sky. cirrus

cirrus

pressure.

Water cycle
Wind
1. Jose notices a puddle of water on his way
home from school. The next day the puddle is
gone. What most likely happened to the puddle
of water?
1. Air flows from high dense air to low dense
air. From higher pressure to lower pressure air.
This creates wind.
It evaporated, turned into a gas.
2. Water vapor cools and forms visible droplets
of water in which stage of the water cycle?
Condensation
3. What causes the precipitation stage of the
water cycle?
Water is heated causing it to change into water
vapor
4. When liquid water evaporates into the air it
becomes a gas known as _________.
2. During the day, the land warms faster than a
body of water next to it. (Like a beach) The air
will travel from the denser, cooler water to the
less dense, warmer land. This is called a sea
breeze.
3. At night, the opposite happens. The land
cools off quicker and the air from the denser,
cooler land travels to the less dense, warmer
water. This is called a land breeze.
4. What causes the winds in the Northern
Hemisphere to curve to right and winds in the
Southern Hemisphere to curve to the left? The
rotation of the Earth.
Water vapor
5. What is the above called? The Coriolis
Effect.
5. When precipitation occurs in below freezing
temperatures the result is hail, snow, and sleet.
6. The North and South poles have cold, dense
air which has high pressure.
6. What makes the water cycle possible?
8. Warm, moist air over the equator creates a
zone of low pressure.
Heat from the Sun
7. Do we have the same amount of water on
the earth as we did a million years ago?
Yes
9. Winds are set in motion around Earth by the
air moving from these high pressure zones
toward the low pressure zones.
10. What kinds of winds does the US get?
Prevailing Westerlies
Air Masses
1. A large region of the atmosphere that has
similar properties is called a(n) air mass.
8. I bring in quick, heavy storms. After the
storm, the skies clear up and the weather is
cooler and drier. What front am I?
2. How do air masses get their names? From
the region they come from.
A Cold Front
3. What happens as air masses move? They
bring their conditions with them, (Ex. Warm,
moist air)
9. I bring in light precipitation, winds, and
sometimes fog. It may last a while. The weather
is more humid and warmer. What front am I?
A Warm Front
4. How do air masses move? By the global
winds.
5. When air masses meet, do they mix? No
6. What happens when air masses meet? A
narrow boundary is formed between them
called a front.
7. How is weather affected by a front? Weather
changes rapidly at fronts usually bringing in
rainy, unsettled weather.
