Predictably, the tourist said "of course not, it might fall over." Dr. Alley then pointed outthe many places where rocks clearly had fallen off the cliffs and moved downhill, atwhich point the tourist quickly switched his opinion to the "down-cutting" riverexplanation, with the ranger thoroughly enjoying the show.Points Earned:0/1Correct Answer:EYour Response:B2.Air that passes over the Sierra Nevada from the Redwoods to Death Valley is warmedby roughly 30oF, even if the air goes over at night. Where does the energy comefrom?
A.The heat that had been stored during evaporation from the ocean and was releasedwhen clouds formed on the west side of the SierraB.Sunshine heating the air while it is passing over the mountainsC.Gas-passing marmots, such as George, seen below;D.The rotation of the Earth, which causes winds to curve as they blow over thesurfaceE.Volcanic eruptions from the peaks along the SierraMuch of the sun’s energy that falls on the tropics is stored by evaporating water, and onlylater made so you can feel it (called sensible heat) when condensation reverses theevaporation. If the warming happens at night, then direct warming from the sun cannot becorrect. The Sierra is no longer volcanically active, and volcanoes rarely emit enoughheat in a broad enough zone to affect general winds much. The Earth does rotate, and thisdoes cause winds to curve as they blow over the surface, but that curving doesn’t addheat to the system. And while marmots do produce a little methane, and a bit of heat, theydon’t produce nearly enough to matter to the climate.Points Earned:1/1Correct Answer:AYour Response:A
3.The picture above illustrates what scientific principle?A.The equator is hotter because it rotates faster, and the wind heats the surface as itrotates by, just as Dr. Alley can turn his head rapidly and cause heat by frictionB.The equator is hotter than the pole because the sun hits the equator directly butthe sun hits the pole a glancing blowC.Dr. Alley is undoubtedly the sexiest human being on EarthD.The equator is hotter than the pole because the equator is closer to the sun thanthe poleE.The equator is hotter than the poles because most volcanoes are located near theequator, forced there by the centrifugal force of Earth’s rotation, and Dr. Alleyexhales hot air from his equatorial noseGeometry is the main control on equatorial heating. Although the equator is closer to thesun than the pole, the difference is tiny and matters little to the temperature differencebetween equator and pole. The rotation of the Earth causes winds to turn as they blowover the surface, but does not heat the air. There is no clustering of volcanoes at theequator, and the heat from volcanoes is tiny compared to the heat from the sun. And weare quite confident that several celebrities and politicians believe that they are the world’ssexiest human being, so Dr. Alley’s standing cannot be “undoubtedly” claimed.
