- 1. Multiple Choice
The Sun warms the atmosphere and drives convection currents because
warm air is less dense and rises
warm air is less dense and sinks
warm air is more dense and rises
warm air is more dense and sinks
- 2. Multiple Choice
Why does the Earth experience unequal heating?
The oceans are not equally distributed around the Earth.
The Earth's revolution brings it closer to the Sun at certain points during the year.
The Earth's axis is tilted.
The atmosphere is not equally distributed around the Earth.
- 3. Multiple Choice
What is the primary or most important factor that influences climate?
latitude
longitude
elevation
climate zone
- 4. Multiple ChoiceWhy is the Equator warmest?Because it is closest to the sun.Because it receives the most direct sunlightBecause no clouds form here.Because it is far from the sun
- 5. Multiple Choice
Surface currents are created by
wind (atmospheric circulation)
seasons
proximity to land
underwater geography
- 6. Multiple Choice
What type of heat transfer is happening in the atmosphere of each cell?
Convection Cells
Radiation Cells
Conduction Cells
- 7. Multiple Choice
A map of sea surface temperatures is provided. The patterns that are observed are due to the fact that
the earth is wider at the equator, so this area spins faster than the poles.
the equator receives more of the Sun's radiation than other parts of the Earth.
the salt content is greater at the poles than at the equator.
the warm, less dense water near the equator sinks, while the colder water rises.
- 8. Multiple Choice
What has the highest albedo?
the oceans
Ice in the Arctic or Antarctic
the ground
roads
- 9. Multiple ChoiceAlbedo can best be described as...the temperature at the equatorthe amount of solar radiation absorbedthe amount of solar radiation reflectedthe air pressure during El Nino
- 10. Multiple ChoiceWhat is the correct order of earth's atmospheric layers from bottom to top?Stratosphere, Mesosphere, Troposphere, Thermosphere, Exosphere.Stratosphere, Troposphere, Mesosphere, Thermosphere, Exosphere.Stratosphere, Troposphere, Thermosphere, Mesosphere, Exosphere.Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.
- 11. Multiple ChoiceWhat is the atmospheric layer closest to the surface?tropospherestratospheremesospherethermosphere
- 12. Multiple ChoiceWithin the stratosphere is the ozone layer. What does the ozone layer do?It protects us from meteorsIt protects us from violent solar flaresIt protects us from ultra violet radiationIt helps us breathe
- 13. Multiple Choice
Which would you expect to have the lowest albedo?
dark soil
white sand
ice and snow
deep sea water
- 14. Multiple Choice

- 15. Multiple ChoiceMelting ice caps will cause the poles to have a ____________ albedo.higherlowersame
- 16. Multiple ChoiceCurrently, about 10% of Earth is covered with ice year-round. If this ice melts, what could happen to Earth’s temperature?IncreaseDecreaseRemain the SameNot enough information
- 17. Multiple Choice
Objects in the NORTHERN Hemisphere deflect to which direction due to the Coriolis Effect?
Left
Up
Down
Right
- 18. Multiple Choice
Westerlies blow in which direction?
West to East
North to South
South to North
East to West
- 19. Multiple Choice
The Coriolis effect causes ___________.
the Earth to rotate on its axis
earthquakes
global winds to move in a curved path instead of a straight line
the Earth to revolve around the sun
- 20. Multiple ChoiceIf the Earth did not rotate, air at the Equator would simplySink and move toward the poles.Rise and move toward the poles.Stay stationary.None of the above.
