Question

Geothermal energy is an alternative energy source, although it is not resourceful enough to replace more than a minor amount of the Earth’s energy needs. Why is this? A. The center of the Earth is not hot enough to make a significant energy contribution. B. Once the cool water is poured down the well and filters through the rocks, the rocks cool off and are no longer hot enough to turn water into steam. C. Drilling through the Earth to reach areas hot enough to create steam is possible, but very expensive and difficult. D. There are only a few places where the Earth’s core is hot. It is cool in places like Antarctica.
