The high-water position corresponding to a tidal crest is called what?

• A. Low Tide
• B. High Tide
• C. Mean Sea Level
• D. Meteorological Tide

Answer: (B)

When a tidal crest passes, the water reaches its highest level in the tidal cycle. That maximum height is called high tide. The crest is the bulge created mainly by the Moon’s gravity (with some influence from the Sun), and when this bulge aligns with the coastline, the water level rises to its peak for that cycle. Mean sea level is just an average water level over time, not the instantaneous high point, and a meteorological tide refers to water level changes caused by atmospheric conditions rather than the astronomical tide. Low tide is the opposite, the minimum water level.
