Which boundary … Inge Lehmann ForMemRS (13 May 1888 – 21 February 1993) was a Danish seismologist and geophysicist. In 1936, she discovered that the Earth has a solid inner core inside a molten outer core. Before that, seismologists believed Earth's core to be a single molten sphere, being unable, however, to explain careful measurements of seismic waves from earthquakes, which were inconsistent with this idea. Lehmann analysed the seismic wave measurements and concluded … increase flyer speed ark

How Inge Lehmann Discovered the Inner Core of the Earth

WebEventually, she had an idea: a solid inner core inside the soft, molten outer core, which would reflect some P-waves, causing them to end up in the shadow zone. Her subsequent calculations,... Webexistence of an inner core is, at least, not contradicted by the observations; these are, perhaps, more easily explained on this assumption. Inge Lehmann (Lehmann, 1936) The rst results for the properties of the inner core were naturally approximate. Much has been written about it, but the last word has proba-bly not yet been said.
