Flexi Says: The temperature of Earth's crust varies considerably. The top of Earth's continental crust is exposed to the atmosphere, and therefore has temperatures in the same range as Earth's surface temperature which averages about 14°C (57.2° F). The top of the oceanic crust is at the bottom of the ocean, where the temperature averages 0-3° C (32-37.5° F). The bottom of Earth's crust ranges from 200° C (392° F) to 400° C (752° F).
