Which option identifies the energy source represented in the following scenario? An enterprising homeowner decides to heat her swimming pool by running pool water through a black housing sandwiched between two sheets of glass.

hydroelectricity
solar heat
biomass
geothermal

Solar Heat

Explanation:

Hydroelectricity uses the movement of water to create electricity. Biomass energy is power produced by living organisms. Geothermal energy is thermal energy generated from the Earth. These can all be ruled out seeing as though none of these are involved in this scenario. Black absorbs heat at a higher rate than other colors and we can assume this heat is produced by the sun hitting the glass.
