Energy can be extracted from tides by
A) the rise and fall of the water.
B) the horizontal movement of water in tidal currents.
C) the declination of the tides.
D) only from diurnal tides.
E) the rise and fall of the water and the horizontal movement of water in tidal currents.

Question

Quizplus · Accepted Answer

Tidal energy can be extracted both by the rise and fall of the water (known as tidal range energy) and the horizontal movement of water in tidal currents (known as tidal stream energy). Therefore, option E is the correct choice as it includes both of these methods. Option D is incorrect because energy can also be extracted from semidiurnal tides. Option C is incorrect as declination refers to the position of the Moon in the sky and has no direct relation to tidal energy extraction.
