Central Core Of Earth Is warmer Than Estimated Easrlier

New study revealed that the central part of earth called core is far warmer than indicated in the data collected earlier. Now it is estimated as 6000 degrees celcius that is equal tothe temperasture of sun surface. It was discovered to have solid inner core distinct from its outer core in 1936 by siesmologist Lnge Lehmann who deducted its presence from earthquake-generated siesmic waves that reflect off the boundary of the inner core and can be detected by sensitive siesmographs on the easrth surface.
