What term is the difference in height between consecutive high and low tides?

• A. Tidal Datum
• B. Tidal Range
• C. Tide
• D. Authigenic Sediment

Answer: (B)

The amount of water level change between high and low tides is described by the tidal range. It’s the vertical distance between a high tide and the following low tide, and it can vary by location and over the cycle (being larger at spring tides and smaller at neap tides). A tidal datum is simply the reference level used to measure tides (like mean sea level), a tide is the actual rise and fall of water, and authigenic sediment is sediment formed in place, not related to the height difference of tides.
