In 1977, researchers from the Woods Hole Oceanographic<br />

Institution sent Alvin, a human-operated deep submergence vehicle,<br />

to the bottom <strong>of</strong> the Galapagos rift. <strong>The</strong> Galapagos rift is interesting<br />

for two reasons. First, it is about a mile and a half deep, and second,<br />

it lies at the intersection <strong>of</strong> three tectonic plates, which means that<br />

it’s geologically very active.<br />

<br />

<strong>The</strong> researchers from Woods Hole discovered some interesting<br />

volcanic vents—black smokers<br />

into the ocean. Like geysers, these hydrothermal vents were shafts<br />

to a deeper layer <strong>of</strong> the Earth’s core. Because the plates meet at a<br />

joint, the magma underneath can pool closer to the surface. This<br />

causes heat and metals from deeper in the Earth to come closer<br />

to the bottom <strong>of</strong> the ocean, and these can move upward through<br />

a weak spot or a hole. <strong>The</strong> water coming out <strong>of</strong> these vents can<br />

reach 750° F.<br />
