Points Earned:1/1 Your Response:E What is accurate about the planet’s climate system? 12.Almost the same amount of energy is received from the sun as is sent back to space, but shortwave radiation is received and longwave radiation is sent back to space. A.Much more energy is received from the sun than is sent back to space, because high-energy shortwave radiation is received but low-energy longwave radiation is sent back. B.Much more energy is sent back to space than is received from the sun, because the planet emits longwave radiation but the sun emits shortwave. C.Almost the same amount of energy is received from the sun as is sent back to space, but longwave radiation is received and only energy stored by evaporation is sent back to space. D.Much more energy is received from the sun than is sent back to space, because high-energy longwave radiation is received but low-energy shortwave radiation is sent back. E.Energy in equals energy out, to very close approximation. We actually send back the tiniest bit more, because the Earth makes a little energy radioactively and because we are mining stored energy (fossil fuels) and burning it, and some of that goes to heat the atmosphere but some is lost to space. But, these differences are tiny tiny tiny. (Lie in the sun on the grass on a hot day, and see if you can tell whether the sun or the Earth is supplying the most heat to your skin…). We receive shortwave—visible light—and send back longwave—infrared. Points Earned:1/1 Your Response:A In the photo above, when Dr. Alley slices his finger through the sand, he is recreating on a smaller scale what type of geologic process? 13.The action of Chuck Norris karate chopping someone. A.The action of earthworms burrowing in loose soil. B.The action of waves making a beach in Hawaii. C.The action of an earthquake tearing apart continents. D.The action of mass wasting, as soil and rock collapses off of newly steep canyon walls initially carved out by water. E.
Despite any passing resemblence, Dr. Alley is not using martial-arts techniques to extract money from sand. Instead, he is showing how a river carves a canyon, which then widens as mass wasting occurs on the steep new walls. Points Earned:1/1 Your Response:E Sam Ascah is standing on sand and gravel in a pothole, where a stream swirls during the short but intense thunderstorms of Zion National Park. And next to that stream, the other picture shows the sandstone and the hang-on-so-you-don’t-fall-over-the-cliff chain along the trail. A likely interpretation of these features is: 14.The potholes and the grooves behind the chain were gnawed by giant beavers. A.The potholes and the grooves behind the chain were gnawed by giant marmots. B.The stream swirled rocks around and cut the potholes, and even bounced up the cliff to cut the notches behind the chain.
