Question

why is hydropower considered a renewable energy source?
○ it uses flowing water that is naturally replenished.
○ it produces more soil for farming.
○ it increases river flow permanently.
○ it requires fossil fuels to operate.

Explanation:

To determine why hydropower is renewable, we analyze each option:

• Option 1: Hydropower doesn't use fossil fuels (fossil fuels are non - renewable, so this is incorrect).
• Option 2: Hydropower doesn't permanently increase river flow (and river flow increase isn't related to renewability).
• Option 3: Hydropower has no direct link to producing more soil for farming, so this is irrelevant.
• Option 4: Hydropower uses flowing water (from the water cycle, which naturally replenishes water), so this fits the definition of a renewable energy source (energy from a naturally replenished resource).

Answer:

It uses flowing water that is naturally replenished.
