Question 6 • AZ-Earth and Space Science B

Why are electrical outputs from a turbine generator highest during a spring tide?

Answer
A
A high tide comes in faster.
B
The gravitational pull of the moon is less.
C
The Sun and the moon pull in opposite directions.
D
The difference between high tide and low tide is the greatest.

Explanation

Spring tides have the largest tidal range: the difference between high tide and low tide is greatest. This creates a greater flow of water through a turbine as tides rise and fall, producing more electrical output. The correct choice is “The difference between high tide and low tide is the greatest.”
