How did inge lehmann discover the inner core
WebEarth's inner core is the innermost geologic layer of planet Earth.It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius.. There are no … WebInge Lehmann was a Danish seismologist–a physicist who studied waves in the Earth’s crust–active in the mid-20th century. She is most remembered for her theory of the Earth’s solid inner core, based on her work on seismic waves caused by earthquakes. Inge Lehmann was born in Copenhagen, Denmark on May 13, 1888.

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 …
