WebIn 1936 she published the paper that sealed her place in the history of geophysics. Known simply as “P’ (P-prime),” the paper suggested a new discontinuity in the seismic structure of the Earth, now known as the Lehmann discontinuity, a region that divides the core into inner and outer parts. Web2 de ago. de 2024 · Earth was discovered to have a solid inner core distinct from its molten outer core in 1936, by the Danish seismologist Inge Lehmann, who deduced its presence by studying seismograms from earthquakes in New Zealand. A few years later, in 1940, it was hypothesized that this inner core was made of solid iron. What created Earth’s core?

How Inge Lehmann Discovered the Inner Core of the Earth

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 … WebDiscovery of the Inner Core by Inge Lehmann in 1936 - YouTube This video is featured in the Deep Earth Explorers Exhibit at the Sedgwick Museum of Earth Sciences.
