Lesson 1 Splash
How does the Sun warm Earth? 180° sunlight
150° sunlight
120° sunlight
90° sunlight
Lesson 1 a
What are the layers of the atmosphere?
thermosphere
mesosphere
stratosphere
troposphere
Lesson 1 b
What changes air pressure?
• volume
• temperature
• height above Earth’s surface
• amount of water vapor
lower air pressure at top of mountain
higher air pressure at sea level
Lesson 1 c
What are global winds?
polar easterlies
prevailing westerlies
trade winds
prevailing westerlies
polar easterlies
heated air
cooled air
wind
Key
Lesson 1 d
trade winds
What are local winds?
sea breeze day
land breeze day
Key
warm air
cold air
Lesson 1 e
How do we measure air pressure and wind?
aneroid barometer
anemometer
Lesson 1 f
What causes winds?
Main Idea
Heat energy from the Sun causes changes in
air pressure. High-pressure air moves toward
low-pressure air. The moving air is wind.
Lesson 1 Main Idea Review
The condition of the troposphere at a particular
time and place is called ____________.
____________ is the force put on a given area
by the weight of the air above it.
____________ is the solar energy that reaches
a planet.
insolation
Vocabulary
air pressure weather

Insolation
Lesson 1 Vocab Review a
____________ blow steadily over long distances
in a predictable direction.
____________ is the amount of water vapor in air.
The ____________ is the layer of gases closest to
Earth’s surface.
A ____________ measures atmospheric pressure.
global winds

Lesson 1 Vocab Review b
How does the heat energy over
an area at the equator compare
to an area at the poles?
Heat energy is
spread over a
greater area at
the poles.
Heat energy
strikes Earth
more directly at
the equator.
Compare and
Contrast
End of Lesson
The Sun
creates
heat energy.

How do clouds form?
Lesson 2 a
Clouds form when water vapor in the air cools
and condenses around tiny particles of dust
How does precipitation form?
rain sleet hail snow
Lesson 2 b
What are air masses and fronts?

mP maritime polar cool, moist air
continental polar cold, dry air

continental tropical hot, dry air
Lesson 2 c
What are highs and lows?
Low-pressure Systems
warmer, humid air
High-pressure Systems
colder, drier air
Lesson 2 d
What do weather maps tell you?
A weather map shows the weather
in a specific area at a specific time.
Lesson 2 e
What can water vapor form?
Main Idea
Water vapor can form clouds,
fog, rain, hail, sleet, or snow.
Lesson 2 Main Idea Review
An _____________ is a large region of air
that has a similar temperature and humidity.
A _____________ shows the weather in a
specific area at a specific time.
A _____________ is the meeting place
between two different large air masses.

Lesson 3 a
What are winter storms?
Lesson 3 b
In the United States, a blizzard is a snowstorm with 35-
mile-per-hour winds and enough snowfall that you can
only see up to one quarter of a mile.
What are tornados?
A tornado is a rotating, funnel-shaped
cloud with wind speed up to 500
kilometers (300 miles) per hour.
Lesson 3 c
What are hurricanes?
A hurricane is a very large, swirling storm
with very low pressure at the center, and
wind speeds greater than 119 km/h.
Lesson 3 d
airplane
Doppler radar How are storms tracked?
weather balloons
Lesson 3 e
What causes storms?
Main Idea
Storms are caused by the
collision of air masses that
have different characteristics.
Lesson 3 Main Idea Review
A ____________ is a snowstorm with 35-mile-per-
hour winds and enough snowfall that you can only
see up to one quarter of a mile.
Hurricane winds can cause waves to form a bulge
of water in the ocean known as a ____________.
A ____________ is any storm with a low-pressure
center that causes a circular pattern of winds to
form.

Lesson 4 Splash
What is climate?
Climate means the average
weather of a place.
Lesson 4 a
What affects climate? • distance from water
• ocean currents
• winds
• altitude
• mountain ranges
Lesson 4 b
What is El Niño?
normal conditions El Niño conditions La Niña conditions
El Niño occurs every two to seven years
when the cold current sinks and stops
pushing cold water up to the surface.
Lesson 4 c
How is climate determined?
Main Idea
Climate is determined by looking at the
average weather patterns in an area or
the type of plant growth in an area.
Lesson 4 Main Idea Review
Every two to seven years, the cold current sinks
and stops pushing cold water up to the surface
causing a change in weather conditions known
as ____________.
____________ is the average weather of a place.
A ____________ is a constant movement of ocean
water.
A ____________ is the dry area on the leeward
side of the moutain.
