Which tide features the highest high tides and the lowest low tides?

• A. Spring tide
• B. Neap tide
• C. High tide
• D. Ebb tide

Answer: (A)

Tidal range is greatest when the Sun’s gravity reinforces the Moon’s gravity on Earth. When the Sun, Moon, and Earth line up during a new moon or a full moon, their gravitational pulls combine, pulling ocean water in the same directions. This makes the high tides higher and the low tides lower—the largest daily difference. That is what we call a Spring tide. The term isn’t about the season; it describes this stronger tidal effect produced by the alignment of the two bodies. In contrast, when the Sun and Moon are at right angles relative to Earth (between new and full moon), their gravitational effects partially cancel. The result is a smaller tidal range, known as a neap tide. High tides aren’t as high and low tides aren’t as low during neap tides. The words high tide and ebb tide describe general parts of the cycle—the peak water level and the falling water—without naming the extreme range situation. So the scenario with the strongest difference between highs and lows corresponds to the Spring tide.
