What is _____________________ and what causes it?
 _________________ from the sun does not heat Earth equally in all
places at all times.
 Convection: the process by which air, or other matter, rises or sinks
because of differences in temperature.
 Convection occurs when gases or liquids are heated_____________.
The cycle continues
 Heated air rises…. WHY?
 This causes cooler air to sink…WHY?
The creation of winds…
 Because warm air is ____________ __________than cool air is,
warm air exerts________ pressure than the same volume of cooler
air does.
 So, the atmospheric pressure is lower _____________ a mass of
warm air.
 As__________, ________ air moves into a low-pressure region, the
less dense, _________air is pushed upward. These pressure
differences, which are the result of unequal heating that causes
convection,__________________!

Red is warm and less dense blue is cool and more dense

Remember…
 Air moves from _________________regions to low-pressure regions.
 High-pressure regions form where cold air ________toward Earth’s
surface.
 Low-pressure regions form where warm air rises ________from
Earth’s surface.
Coriolis Effect
 The tendency of a moving object to follow a __________ path rather
than a straight path because of the rotation of Earth.
 Winds curve as a result of the_______________ _____________.
 The CE deflects moving objects along a path that depends on the ____________, ____________ and _________of the object.
 Defected to __________ in NH and ________in SH
 The faster an object travels, the ____________ the Coriolis effect on
that object is.
Clouds
 Collections of small water droplets or ice crystals that fall slowly
through the air.
 Fog is actually a cloud that forms near or on Earth’s surface.
 Classification:
o _______________
o Cumulus clouds
o _______________
o Stratus Clouds

 Have a flat, uniform base and begins to form at very__________
_______.
 Form where a layer of warm, moist air lies above a layer of cool air.
 Draw one here
Cumulus Clouds
 Low-altitude, billowy clouds that have a top that resembles
_______________ __________and a dark bottom.
 Look fluffy
 Form when ____________, moist air rises and cools as the cooling
air reaches its dew point, the clouds form.
 Draw one here
Cirrus Clouds
 Feathery clouds that are composed of ice crystals and that have the
__________ ____________of any cloud in the sky.
 Cirro- and cirrus mean ____________
 Form at altitudes above 6,000 meters.
 Weather Disasters-Hurricanes

Weather Forecasting
 The weather used to be attributed to Gods.
 Weather observers measure precipitation, _____________and
humidity. They note the type, amount and ____________of cloud
cover.
 Data collected is transferred onto weather maps.
 Symbols and ___________are used on maps and understood by
meteorologists around the world.
Weather Forecasting
 Common symbols describe cloud cover, wind speed, wind direction
and ____________ ________________ such as precipitation and
storm activity.
 Isotherms – lines that connect points of equal temperature
 ___________- lines that connect points of equal atmospheric
pressure.
 _______________ spaced isobars indicate a rapid change in speed
and direction of wind.
 Isobars that form circles indicate centers of high or low pressure.
