This is the amount of water in
the air.
What is humidity?
This is used to measure the
amount of heat energy in an
area.
What is a thermometer?
This is used to measure the
air pressure in an area.
What is a barometer?
When wind speeds reach 74
mph, these storms occur over
large bodies of water.
What are hurricanes?
Turn to page 317. What is
the first step in the
formation of a tornado
What is when air spins from the
bottom of a thunderstorm?
This is what causes wind.
What is the uneven heating of
Earth’s surface?
These winds travel over a short
distance and are caused by the
uneven heating of land and sea.
What are local winds?
Winds that travel over long
distances and in only one
direction.
What are global winds?
Without wind, all of Earth’s
precipitation would fall here.
What is the ocean (right where it
evaporated)?
Name the diagram.
What is a sea breeze.
A large body of air that has
the same temperature and
humidity.
What is an air mass?
This forms when two air
masses collide.
What is a front?
When these move through an
area, they cause the weather
to become humid and warm.
What are warm fronts?
These cause cool, dry weather
when they have passed
through an area.
What are cold fronts?
These cause warm air to be
pushed up rapidly, often
causing thunderstorms.
What are cold fronts?
These clouds are in a “heap”.
They look like cotton balls and
indicate fair weather.
What are cumulus clouds?
These clouds form high in the
troposphere and are made up
of ice crystals.
What are cirrus clouds?
These clouds form low in the
atmosphere. They “spread
out” and cover the sky.
What are stratus?
These clouds are massive in
size and produce heavy rains.
What are cumulonimbus clouds?
On this weather map,
where would clouds be
least likely to form?

Region 1. High pressure systems usually
have fair weather. In low pressure
systems, warm air holding water vapor
rises. Water vapor condenses on dust
particles and forms clouds.
The main job of oceans.
What is to keep Earth’s climate
mild by removing heat (cooling)
warm areas and distributing that
heat to cold areas?
When currents bring warm
water to a cold area, it is
evaporated and moved over
land as part of this cycle.
What is a convection current?
The main source of energy for
ocean currents.
What are global winds?
This is why warm air holds
more water than cold air. It is
also why warm air rises.
What is the fact that warm air
is less dense than cold air?
This is how oceans keep
Earth’s climate mild.
Ocean currents help to bring warm water from the
equator to areas of the Earth that are closer to the
poles and colder. When that warm water reaches
land in those areas, it is evaporated and moved
over land as water vapor by convection currents.
There, it condenses to water and releases heated
energy into the atmosphere, warming the climate
of that cold area. This also keeps the tropical
regions near the equator a little cooler.
