Uranium atoms are split to create a tremendous amount of energy in a (a)   power plant.

• biomass

• geothermal

• nuclear

• hydroelectric

Answer explanation

Uranium atoms undergo fission in a nuclear power plant, releasing a large amount of energy. This process is distinct from biomass, geothermal, and hydroelectric power, which utilize different energy sources.
