Is inner core of earth solid
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. … Zobacz więcej 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 Zobacz więcej Seismic wave velocity The velocity of the S waves in the core varies smoothly from about 3.7 km/s at the center to about 3.5 km/s at the surface. That is considerably less than the velocity of S waves in the lower crust (about 4.5 km/s) and less … Zobacz więcej Many scientists had initially expected that the inner core would be found to be homogeneous, because that same process should … Zobacz więcej Because the inner core is not rigidly connected to the Earth's solid mantle, the possibility that it rotates slightly more quickly or … Zobacz więcej Seismic waves Almost all direct measurements that scientists have about the physical properties of the inner core are the seismic waves that … Zobacz więcej There is still no direct evidence about the composition of the inner core.
