NASA: Earth has multiple layers: the crust, the mantle, the liquid outer core and the solid inner core.

Earth's internal engine is running about 1,000 degrees Celsius (about 1,800 degrees Fahrenheit) hotter than previously measured, providing a better explanation for how the planet generates a magnetic field, a new study has found.
A team of scientists has measured the melting point of iron at high precision in a laboratory, and then drew from that result to calculate the temperature at the boundary of Earth's inner and outer core — now estimated at 6,000 C (about 10,800 F). That's as hot as the surface of the sun.
The difference in temperature matters, because this explains how the Earth generates its magnetic field. The Earth has a solid inner core surrounded by a liquid outer core, which, in turn, has the solid, but flowing, mantle above it. There needs to be a 2,700-degree F (1,500 C) difference between the inner core and the mantle to spur "thermal movements" that — along with Earth's spin — create the magnetic field.

Ping.
I was reading that one of the theories about mars is that a major impact disrupted the convection currents and halted any plate tectonics that may have been going on there.
The instrument of measurement and the scale were changed ~ the temperature is presumably the same as it ever was ~ pretty hot!
Global warming?
Still not quite up to the “several million degrees” that Al Gore said. ROFL!
Where is your proof?
That proof enough for ya? teehee
Globalist warning no doubt.
Wow, now it all makes sense.
The earth has a feevah!!
I believe.
It’d be really nice if it would warm up my area about 30 degrees, then.
