When Earth, the Moon, and the Sun align in a straight line, the tidal range is largest. What is this phenomenon called?

• A. Spring tide
• B. Neap tide
• C. High tide
• D. Tidal range

Answer: (A)

Tides are driven by gravity from the Moon and the Sun, and the size of the tidal range depends on how those gravitational pulls line up. When Earth, Moon, and Sun are in a straight line, their gravity reinforces each other, pulling on the oceans in the same direction. That makes high tides higher and low tides lower, increasing the difference between them. This strongest effect occurs during the alignments at new moon and full moon, and it’s called a spring tide. The name isn’t about the season; it comes from the idea of tides “springing forth” to greater extremes. Neap tides happen when the Sun and Moon are at right angles, giving a smaller tidal range. High tide is the peak water level, not the overall phenomenon, and tidal range simply refers to that difference in water height.
