The Earth's crust is not a uniform temperature. It varies greatly depending on depth, location, and geological activity.

Here's a breakdown:

* Surface: The surface temperature of the Earth's crust fluctuates greatly depending on location and time of day.

* Shallow Crust: The temperature increases gradually as you go deeper, typically around 1-3 degrees Fahrenheit per 100 feet.

* Continental Crust: The average temperature at the base of the continental crust (around 25 miles deep) is estimated to be between 1,600 and 2,200 degrees Fahrenheit.

* Oceanic Crust: The average temperature at the base of the oceanic crust (around 6 miles deep) is estimated to be around 1,800 degrees Fahrenheit.

So, there is no single answer to "how many Fahrenheit is the crust."
