The velocity of a rotary tidal current will increase when the Moon is _______________.
AI Explanation
The correct answer is D) All of the above.
The velocity of a rotary tidal current will increase when the Moon is full, at perigee, or new. This is because the gravitational pull of the Moon is the primary driver of tidal currents, and the Moon's position relative to the Earth affects the strength of this gravitational pull.
When the Moon is full or new, its gravitational pull is aligned with the Sun's, resulting in stronger "spring tides" and increased tidal current velocities. When the Moon is at perigee (the point in its orbit closest to the Earth), its gravitational pull is also stronger, leading to faster tidal currents.
