Chapter 7 Concepts Quiz

All of the following are true of El Nino-Southern Oscillation (ENSO) EXCEPT

• it occurs regularly, every 5 years in the Pacific

• the prevailing winds in the tropical Pacific weaken and change directions

• the warming of the western Pacific causes a reduction in upwelling nutrients and an increase in rainfall

• the typical monsoon season in the eastern Pacific is reduced, and sometimes there are droughts

Which way do hurricanes rotate in the Northern Hemisphere?

• It depends on the surface temperature of the ocean

• Clockwise

• Counterclockwise

• It depends on the level of solar energy input

The greenhouse effect can best be described as

• a natural warming of the stratosphere because of the hole in the ozone layer

• an unnatural change in the Earth's climate because of warming air

• the warming of the troposphere, caused by the absorption of heat by greenhouse gaes

• the unnatural heating of the atmosphere by CO₂ from fossil fuel combustion

As one climbs a mountain from the windward side, the elevation change causes a change in biomes. Which of the following is a change cause by elevation increase?

• Biomes become more diverse because of the decrease in temperature.

• Precipitation increases as air rises and water vapor condenses, resulting in vegetation that thrives with a large amount of moisture.

• Temperature is highest on mountaintops because they are closer to the sun and therefore receive more solar radiation

• The land becomes arid, resulting in the growth of different types of vegetation

Long-term differences in which two variables are the primary determinants of climate?

• Temperature and cloud cover

• Precipitation and temperature

• Precipitation and soil type

• Temperature and soil type
