How does the temperature of earth's crust compare to the temperature of earth's interior?

Answer 1

It's hard to say, because nobody's really been inside the crust. But we can make guesses based on what we think is down there and what happens to come out from time to time.

Generally, the core is thought to reach temperatures about about 7000 K. 0 K is absolute zero, and a hot day on the surface of the crust would be around 300 K, so the core is probably about 23 times hotter than the surface. And that's on a hot day!

But there's also a fair amount of variation. Basically, the further out you get, the colder you get. So there's a whole gradation between 7000 and the near 0 of space. It just depends on where you choose to stick your thermometer.

Answer 2

Temperature Of The Crust

Answer 3

The crust is cold compared to the mantle but its not all that cold. The mantle is ~2,000K or so and the surface is ~260K if you don't factor in the solar flux. If the interior of Earth cooled down the surface would freeze solid.

Answer 4

evey km down there is a rise in temp of 30degrees C
