Have scientists ever figured out why the Earth doesn't melt?

With all of that lava in the center?

    It HAS melted----That's why there is so much LAVA inside.----Actually it hasn't solidified YET enough to melt.  Only less than 100 miles of the outer surface of the 8000 mile sphere (the crust) has solidified from being exposed to air and space.

    Ever eat a burrito?  Specifically, a burrito that seems to be the perfect temperature, but when you bite into it, the contents inside are scalding hot?  The exterior radiates heat.  The interior has a harder time doing that.

    because the outer layers constantly shed heat into the atmosphere, which keeps the minerals in a solid state, creating an outer "shell" that contains the liquid core.

    They did the math using the basic laws of physics. That is how they do a lot of their work when they can't do direct measurements.

    All the stuff between where we are and the lava is makes a good insulator.
