Why is it hotter at the equator than at the Poles?
a) The angle at which sunlight hits the earth leads to a given amount of solar energy being spread over a smaller area at the equator than at the Poles.
b) The increased rotational speed of the earth at the Poles creates strong winds that increase radiant cooling.
c) Greater cloud cover at the equator leads to a greater "greenhouse" effect than at the Poles.
d) The water in the oceans has a high heat capacity, and there is significantly more water near the equator than at the Poles.
e) All of the above are responsible for the higher average temperature at the equator than at the Poles.

Why do beaches on the west coast of the United States
have colder water than beaches on the east coast?
a) The ocean currents in the northern hemisphere
rotate in a clockwise direction, so water off the
coast of California has just come from the cold
north, while water off the coast of New York has
just come from the warm south.
b) West coast beaches are not colder than east coast
beaches. Ocean temperatures depend only on
latitude.
c) The Pacific Ocean is deeper than the Atlantic
Ocean, so more of the sun’s heat is absorbed by
the colder, deep water, reducing the water
temperature at the west coast beaches.
d) Trade winds blowing north from the Tropic of
Cancer in the Pacific Ocean sweep the warm air
away from the west coast, taking with it much of
the warmth of the water.
e) Deep water upwellings bring cool water to the
west coast beaches, while the surface currents on
the east coast cause downwellings, sending
warm surface water to depths where it is less
likely to be lost through evaporation.

When moist wind from an ocean blows onshore toward a mountain range:
a) as the air rises, it pulls moisture from the ground, causing the higher elevations to be drier
b) as the air goes over the top of the mountain and falls back down toward lower elevations, it holds less moisture, creating a "rain shadow" zone of unusually high precipitation.
c) as the air rises, it holds less moisture, causing the dissipation of all clouds.
d) as the moist air goes over the top of the mountain and falls back down toward lower elevations, it holds even more moisture, creating a "rain shadow" desert with very little precipitation.
e) None of the above are correct.
