en.wikipedia.org/wiki/Inner_core

Earth's inner core is the innermost geologic layer of the Earth. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 20% of the Earth's radius and 70% of the Moon's radius. There are no samples of the Earth's core available for direct measurement, as there are for the Earth's mantle.

en.wikipedia.org/wiki/Crust_(geology)

The crust is a thin shell on the outside of the Earth, accounting for less than 1% of Earth's volume. It is the top component of lithosphere: a division of Earth's layers that includes the crust and the upper part of the mantle. The lithosphere is broken into tectonic plates that move, allowing heat to escape from the interior of the Earth into space.

"Earth's core temperature is estimated at around 5000 to 7000 degrees Celsius." 5300–7300 K: No one can really explore the earths interior. Scientist obtain information about the characteristics of the earth's interior by studying earthquake records. Earthquake waves help scientists figure out the distances to each of the section of the earth ...

Core: The Earth has a iron-nickel core that is about 2,100 miles in radius. The inner core may have a temperature up to about 13,000°F (7,200°C = 7,500 K), which is hotter than the surface of the Sun. The inner core (which has a radius of about 750 miles (1,228 km) is solid.

The outer core, and the mantle both have a similar temperature. This is about the same as the surface of the sun. That is why very hot lava is yellow - that indicates its temperature.
