Question:
Geology proves that as we dig deep into the ground, the temperature rises. That being so we should expect sea water at 4 or 5 miles deep down to be boiling. But that is not happening. Why?



Replies:
It is because of the way heat is transferred between the interior of the earth and the surface, and the way heat is transferred between the different depths of the ocean. In Earth's crust, heat must diffuse through solid rock. In the oceans, cold, dense water sinks and warm water rises. Can you see how these different mechanisms will produce different temperature profiles in Earth's solid crust and its liquid oceans?
