Help quick? Which of the following statements best compares nuclear power and hydropower based on their rates of renewal?
liubo4ka [24]

Answer:

Hydropower has a faster rate because water is continuously being recycled through the hydrogeological cycle.

Explanation:

The source of hydropower is mostly from water which is a part of the hydrogeological cycle. Water is renewed at a faster rate within the weather system from time to time. We can easily forecast and predict an areas potency of generating hydro-electricity. Water is a renewable resources.

For nuclear power, the source is geological. Not all elements are radioactive. A certain condition must be fulfilled for spontaneous radioactivity in an isotope. Minerals are mined for their useful radioactive materials which serves as fuels in nuclear power plant. Geological processes takes a very long time to occur and so the sources of nuclear power is not easily renewed. In fact, they are classified as part of non-renewable resources.
