Question

Which factor contributes to the formation of tides that turn turbines to create energy in the ocean?

wind speed
water density
Earth’s rotation
water temperature

Answer 1

Earth’s rotation.

Tides are produced mainly by the gravitational pull of the Moon and Sun combined with the rotation of the Earth–Moon system, which creates the regular rising and falling of sea level. Wind, water density, and temperature influence waves or local sea level slightly, but they are not the primary cause of tides.
