Tidal energy is a potential renewable energy resource. Which of the following is the main cause for the formation of tidal waves?

Tides form mainly from the combined gravitational pull of both the sun and the moon on the ocean waters.

The moon alone is the stronger single pull but is not the complete cause of tides.

The sun alone exerts a real but weaker tidal pull and is not the sole cause.

Since both bodies act together, none of the above does not apply.

When sun and moon align, their combined pull produces the very high spring tides.

When they are at right angles, the weaker neap tides result.
