[Steve Van Doorn]

I can not find a good source but just look at this pic:

The red area is over 1000 deg C. That thin blue line is the crust with the lower part of the crust over 900 deg C.

Even if the crust of the earth was the best insulator we know of we would still get a lot of heat from it. The earth is a ball of fire with a small thin egg shell. If we don’t get most of our heat from the mantle I would like to understand HOW?

Why does snow accumulate on the earth's surface if what you claim is true?
