Scientists first used seismic waves to determine that the inner core was solid in 1936. Before the discovery by Danish seismologist Inge Lehmann, it was assumed the entire core was liquid since it is exceedingly hot, approaching 10,000 degrees Fahrenheit, about the temperature on the sun’s sur...

In the paper, the researchers argued that the standard model of how the Earth's core formed is missing a crucial detail about how metals crystallize: a mandatory, massive drop in temperature that would be extremely difficult to achieve at core pressures. [6 Visions of Earth's Core] Weirder ...
"We know the Earth's inner core is composed mostly of iron, but we don't really know too much about the behavior of iron under the pressure and temperature at conditions in the core," Gleason said. The metal was subjected to more than 200 billion pascals of pressure, or about 180,000...
There are many different temperatures that are occurring on the crust of the earth. The air you feel right now is the lowest temperature available on the crust. The highest temperature can be as high as 1,600 degrees Fahrenheit. This is the temperature that would allow rocks to melt which ...

sulfuricacid; boil off the oceans by cranking up the temperature to 900 degreesFahrenheit(nearly 500 degreesCelsius), and boost the air pressure high enough to flatten you like a pancake. What you now have isVenus, a rocky planet similar in size to Earth but different in...
U.S. Pat. No. 3,889,455 discloses a method and apparatus for filling the interstitial spacing of the stranded conductor in a high temperature flooding tank. The individual wires are fed into a tank containing the filling material, the material having been heated to allow it to become less...
