Earth's inner core thickness
Earth'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 samples of Earth's core accessible for direct measurement, as there are for Earth's mantle. Information about Earth's core mostly comes fro… WebConclusion: no direct measurements possible, only indirectly derived measurements by the speed of travel from seismic waves. Very important is that the outer core being liquid (and mantle solid), shear waves from earthquakes cannot travel through the outer core. Along with refraction and reflection of P -waves at the core-mantle boundary, this ...
