Question

Tidal energy works using:

• A. average of sea levels of high and low tides.
• B. resisting the formation of tides.
• C. difference in sea levels between high and low tides.
• D. using heat energy in tides.

Answer 1

The correct option is C difference in sea levels between high and low tides.

Due to gravitational pull of the Moon (and the Sun), sea level changes and high tides and low tides are formed. Difference in sea levels between high tides and low tides gives us tidal energy.
