WebStructure of Earth. The Earth's core is the part of Earth in the middle of our planet. It has a solid inner core and a liquid outer core. The temperature of the outer core ranges from 4400 °C in the outer regions to 6100 °C near the inner core. Seismic measurements prove the core has two parts, a "solid" inner core with a radius of ≈1,220 ... WebInner Core: The innermost part of Earth is the core and is about 1500 miles (2414 km) thick. Both the inner and outer cores consist primarily of iron and nickel. They're extremely hot, with temperatures ranging from … teacup tulip hat royale highEarth'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. … See more 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 See more 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 … See more Many scientists had initially expected that the inner core would be found to be homogeneous, because that same process should have proceeded uniformly during its entire formation. It was even suggested that Earth's inner core might be a See more Because the inner core is not rigidly connected to the Earth's solid mantle, the possibility that it rotates slightly more quickly or slowly than the rest of Earth has long been entertained. In the 1990s, seismologists made various claims about detecting See more Seismic waves Almost all direct measurements that scientists have about the physical properties of the inner core are the seismic waves that pass … See more There is still no direct evidence about the composition of the inner core. However, based on the relative prevalence of various chemical … See more The Earth's inner core is thought to be slowly growing as the liquid outer core at the boundary with the inner core cools and solidifies due to the gradual cooling of the Earth's interior (about 100 degrees Celsius per billion years).

"WebThe solid inner core is complex and not yet fully understood. This is hardly surprising given that the temperature of the Earth's core (q.v.) is in the range 5000–6000 K and inner core pressures are 330– 360 GPa. Knowledge of the exact composition and structure of the Earth's inner core would enable a better understanding of the internal " - Description of earth's inner core
