This is from a Science book. I don't know the temperature of the crust, but I do know that the mantle is 870 degrees Celsius, the outer core is 2,200 degrees Celsius, and the inner core is 5,000 degrees Celsius. I hope this helps! :)
Heat = depth. The further down inside the earth you go, the hotter it becomes.
The absolute inner core of the earth, which is mostly iron and nickle, would be around 13,000 degrees (that's hotter than the sun). Then it ranges from 8,000 to 6-7,000 to 1600 to 32 degrees as you come towards the surface.
6000 degrees Celsius
The answer is 1 600 degrees celsius
A few 100 ft it is 52 degree Fahrenheit but as one drill deeper it will come up approximately 1 degree after every 100 foot.
About 6,000 C this is a very COLD part of the earth!
