Neap tide occurs when the Sun and Moon are at right angles, producing which tidal range?

The largest tidal range. The tidal range varies randomly. The tidal range is unaffected by the Moon. The smallest tidal range.

Correct Answer:

The smallest tidal range.

Explanation:

Tides are shaped by the gravity of both the Moon and the Sun pulling on Earth's oceans. When the Sun and Moon are at right angles relative to Earth, their gravitational effects partially cancel each other on the bulges of water. That makes the high tides not as high and the low tides not as low, so the difference between high and low tide—the tidal range—is the smallest during neap tides. The Sun’s pull reduces the Moon’s stronger tidal effect, leading to a subdued overall tide.
