Whose work discovered the Earth's inner core?
Quick Answer
Inge Lehmann discovered Earth's solid inner core in 1936. She inferred it from the way seismic waves traveled through the planet.
The Full Story
Danish seismologist Inge Lehmann analyzed earthquake data and found evidence that Earth has a solid inner core inside a liquid outer core. She published her interpretation in 1936 after studying seismic wave behavior that could not be explained by a completely liquid core. Her work showed that Earth's interior is layered and complex. The inner core is now understood to be mostly iron and nickel under extreme pressure.
