Temperatures tend to be hottest near Earth's equator. There, warm air rises and becomes lighter than the surrounding air. This warm air flows east or west and moves toward Earth's poles. Which of the following is most likely to result from this?
a) A cold front
b) A change in seasons
c) Wind
d) Snow

Earth spins on its axis, creating three belts of circulation. The belts of circulation determine how warm air and surface currents in the ocean will flow. The flow acts to redistribute heat from the Sun
a) only to Earth's equatorial regions.
b) to Earth's inner core.
c) only to Earth's poles.
d) around Earth's surface.

Heat energy causes there to be differences in temperature and pressure on Earth's surface. When water in Earth's oceans and a
a) generates heat by reducing winds and ocean currents.
b) moves heat by creating winds and ocean currents.
c) destroys heat by reversing winds and ocean currents.
d) reflects heat by increasing winds and ocean currents.

Which factor best explains the reason that average summer temperatures are higher than winter temperatures in North America?
a) The Earth is closer to the sun during the summer months.
b) Cyclical activity on the Sun causes more radiant energy to be produced.
c) North America is tilted toward the Sun during the summer months.
d) Ocean water temperatures near the Equator influence North America during the summer.

The Earth moves in predicable patterns. One of these patterns causes the seasons as the Earth moves around the Sun along its elliptical orbit. This movement is referred to as —
a) a rotation
b) an equinox
c) a photoperiod
d) a revolution

An ocean allows a hurricane to grow by supplying it with —
a) snow from freezing waters.
b) water vapor from warm waters.
c) oxygen from cool waters.
d) salt from hot waters.

Tropical depressions tend to originate over —
a) warm oceans, where water is likely to rise as vapor and later fall as rain.
b) large inland lakes, where water is likely to rise as vapor and later fall as sleet.
c) sandy deserts, where water is likely to rise as vapor and remain in the air as clouds.
d) masses of sea ice, where water is likely to rise as vapor and later fall as snow.

During an El Niño weather event, trade winds across the Pacific Ocean weaken, and waters along the coast of Peru and Ecuador become unusually warm. The warmer ocean waters result in —
a) the formation of numerous thunderstorms along the South American coast.
b) many days of clear, cold weather along the South American coast.
c) many days of clear, warm weather along the South American coast.
d) the formation of numerous hurricanes along the South American coast.

Which of the following best describes on significant limitation of local and regional weather forecasting?
a) Global events far away can have significant impacts on local climate.
b) There is limited weather data available to forecasters.
c) Scientists have little knowledge of how variables like atmospheric pressure and temperature affect weather patterns.
d) Historical trends provide the most accurate models for current, daily forecasts, but are not applied correctly by many weathe

In the water cycle, surface water evaporates into the atmosphere, condenses and eventually falls to Earth as precipitation. What part of this system is MOST essential for the water cycle to function?
a) energy from the sun
b) location of rivers
c) human use of water
d) animal use of water

Which physical property of hot air results in the development of convection currents?
a) density
b) humidity
c) mass
d) specific heat

How are air masses classified?
a) by temperature and pressure
b) by pressure and humidity
c) by temperature and density
d) by temperature and humidity

What form of energy causes water in the ocean to evaporate?
a) chemical
b) heat
c) kinetic
d) potential

During the time period that an El Niño is occurring, —
a) there is a buildup of cold water off the west coast of South America.
b) there is a buildup of warm water off the west coast of South America.
c) the trade winds get stronger and cause a cooling of the surface water of the ocean.
d) Antarctica will have a dramatic increase in its temperature.

Lines joining places that have the same temperature are
a) isobars
b) isotherms
c) fronts
d) occluded

Changes in the thickness of polar ice caps likely indicate changes in —
a) solar activity
b) Earth's climate
c) the location of tectonic plates
d) the variety of polar animal species

a) evaporation
b) condensation
c) precipitation
d) convection
