The Earthâs Centre is 1000 Degrees Hotter than Previously Thought. Scientists have determined the temperature near the Earthâs centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago.he layers of the Earth and their temperatures: crust, upper and lower mantle, outer core and solid iron core. Credit ESRF. The Earthâs core consists mainly of a sphere of liquid iron at temperatures above 4000 degrees and pressures of more than 1.3 million atmospheres.
It's called geothermal energy-- from the Greek words geo, or earth, and therme, meaning heat. There is plenty of heat in the center of the Earth. The deeper you dig, the hotter it gets. The core, about 4,000 miles (6,437 kilometers) beneath the surface, can reach temperatures of 7,600 degrees Fahrenheit (4,204 degrees Celsius).
