rain shadow
A(n) _________________________ is often found on the inland side of a mountain range.
The _________________________ is an international agreement that limits CFC production.
Montreal Protocol
During a(an) ____________________ period, winds push warm water eastward in the Pacific Ocean.
b. El Nino
Which of the following statements related to global warming is not accurate?
b. Only fossil fuels, not living plants, release carbon dioxide when burned.
Which of the following would occur if Earth were not tilted relative to the plane of its orbit?
b. Temperate regions would no longer have seasonal changes in climate.
A predicted increase in Earth's average temperature caused by human activities and the subsequent release of gases such as carbon dioxide is known as _________________________.
b. global warming
The _________________________ is a process by which the atmosphere reradiates infrared radiation back to Earth's surface and thereby warms Earth's surface and lower atmosphere.
b. greenhouse effect
Which of the following would not be a consequence of a rise in global temperature?
b. increased polar ice mass
A true statement concerning the physical properties of air is that
b. warm air can hold more water vapor than an equal amount of cold air.
Rain frequently results whenever
b. warm, moist air rises.
During summer in the Southern Hemisphere, the Northern Hemisphere experiences
b. winter.
Water vapor and carbon dioxide reradiate infrared radiation in the atmosphere back to the surface of Earth, so they are called _________________________.
c. greenhouse gases
A true statement about greenhouse gases is that they
