The inner core is made of solid metals, and the outer core is made of liquid metals. What does “plate tectonics” refer to? The theory that the earth’s lithosphere is broken into plates which float on top of the mantle. These plates shift, causing earthquakes. Where do most earthquakes...
Now, the Plume Hypothesis provides a pretty elegant explanation for a volcanic anomaly, like the Hawaiian Islands. But, while it's hypothetically attractive, there's very little direct evidence to support the theory, because so far, no one's been able to actually observe what's happening that...
Explain the phenomenon in nature that is caused by water's properties. Discuss and explain thermocline. What two factors affect the speed of sound in the ocean? Explain how the Theory of Plate Tectonics has influenced the study of marine science in at least three ways. ...
Plate tectonics may be one of the (4)___ triumphs of the human mind, geology"s (5)___ to biology"s theory of evolution. And yet scientists still can"t say when an earthquake will happen. They can"t even come (6)___. What scientists can do right now is make good maps of ...

theory that's been proposed is the plume hypothesis. According to this hypothesis, lumes—um, basically, columns of extremely hot magma—these plumes well up from deep inside the planet's interior—maybe even as deep as its core—and rise all the way up to melt through the Earth's crust...
Then answer the question. Why does the professor ask this: A.To test the students" understanding of plate tectonics B.To describe an event that confuses many scientists C.To point out a theory that has never been confirmed D.To introduce a phenomenon that he intends to explain 点击查看答案...
which means, of course, that volcanic activity there can't be explained simply by plate tectonics. So … how do we explain these volcanic anomalies... these exceptions to the general rule?Well, back in 1963, a geophysicist by the name of Wilson came up with the hot spot theory… to ...
