What is geothermal energy, and what are two ways it is being harnessed?
What will be an ideal response?
Geothermal energy "occurs where the hot molten rock of Earth's interior is close enough to the surface to heat groundwater." Two ways in which geothermal is being used are electrical production and space heating.

Why might the following nuclear reaction not be very good for energy production in a fission reactor?
U ? 
Th + 
He + 3 neutrons
A. Interatomic attraction between the products will impede the separation of the atoms from the unstable nuclei. B. The material only produces a few neutrons so the chain reaction will not be very efficient. C. The mass of the by-products is too high, and therefore, the energy released will not be large enough. D. The reactants are too small to obtain much energy from the missing mass due to the strong nuclear force. E. The products are not the right size to obtain much energy from missing mass due to strong nuclear force.
