What is the term for the difference in water levels between a high tide and a low tide?

• A. Tidal range
• B. Tide height
• C. Wave height
• D. Sea level change

Answer: (A)

The difference in water levels between high tide and low tide is called the tidal range. It’s the vertical distance from the highest water level reached during high tide to the lowest water level reached during low tide in a complete tidal cycle. Gravitational forces from the Moon and Sun drive this movement, and the size of the range can vary by location because coastline shape, water depth, and ocean floor features amplify or dampen the tides. This term is distinct from tide height, which just describes how high the water is at a particular tide, from wave height, which measures the height of surface waves, and from sea level change, which refers to long-term shifts in average sea level rather than the daily rise and fall.
