. 

How does carbon dioxide prevent infrared heat energy from escaping into space?

• It does all of these.

• It absorbs it and redirects some rays back toward the earth.

• It changes the color of the atmosphere to the brown haze we see over cities.

• It reflects sunlight back into space.

Deep ocean currents are created by what two things?

• temperature and fetch

• difference in the heating of land and sea

• salinity and the Coriolis effect

• temperature and salinity

What role does the Coriolis effect have on ocean surface circulation?

• 
  

  It creates temperature and salinity differences, which make deep ocean currents possible.

• It causes currents to deflect to the right in the northern hemisphere and to the left in the southern hemisphere.

• All of these lesson 8.3.

• It causes large-scale fetch to form.

Here is a map showing high pressure on the left and low pressure on the right. Notice the directions (NSEW) are indicated on the map. Which direction will the wind blow at the red spot between the high and low pressure regions? (Hint: Recall how winds flow around high and low pressure areas.)

• toward the south

• toward the north

• toward the east

• toward the west

Which statement best describes the current state of our understanding of the idea of global warming?

• Global warming is absolutely false because ice core data contradicts tree ring data.

• Global warming is a logical inference given the facts that carbon dioxide levels are rising as an effective greenhouse gas.

• 
  

  Global warming is a known fact because most scientists believe it is happening, and all the data shows this to be the case.

• 
  

  Global warming is true because computer models are so good that they can accurately model the most complex of planetary climates.

Which instrument is incorrectly matched with its purpose?

• A barometer measures air pressure.

• An anemometer measures wind direction.

• A psychrometer measures humidity.

• A thermometer measures air temperature.

Four students wrote definitions for the terms weather and climate. Which is the best response?

• Weather is the conditions in the atmosphere over thousands and millions of years, and climate means recent conditions on Earth day by day.

• Weather is what we can actually measure with our instruments, and climate is what we learn from study of past air samples.

• 
  

  Weather is what is happening right now, and climate is from last week.

• Weather is the current conditions in the atmosphere, and climate refers to the long term conditions on Earth.
