Whose research explained why the Earth’s inner core is solid?

Quick Answer

Inge Lehmann is credited with discovering Earth’s solid inner core in 1936. She identified it from seismic-wave behavior.

The Full Story

Danish seismologist Inge Lehmann analyzed earthquake waves and realized that some seismic signals were being refracted by a previously unknown inner region of the core. In 1936 she proposed that Earth has a solid inner core surrounded by a liquid outer core. Her conclusion came from careful interpretation of seismic data, not direct observation. Lehmann’s work was a major step in understanding Earth’s internal structure and the generation of the magnetic field.
