Image Of the Day caption:
MIT-WHOI Joint Program student Emily Sarafian wields a hydraulic jack to demonstrate how to set up a piston-cylinder apparatus. She uses the device to carry out high-temperature, high-pressure experiments on rock samples, simulating conditions inside Earths upper mantle. In research published recently in the journal Science, Sarafian combined two very different approaches to geological researchexperimental petrology and magnetotellurics, a branch of geophysicsand discovered that the mantle beneath the sea floor could be as much as 110?F hotter than previously thought. A hotter mantle would be more fluid, helping to explain the movement of Earth's rigid tectonic plates.
