How many high and low tides occur daily on the Maine coast?

• A. One high and one low
• B. Two highs and two lows
• C. Three highs and three lows
• D. Four highs and four lows

Answer: (B)

The Maine coast typically experiences a semidiurnal tide pattern, meaning there are two high tides and two low tides each tidal day. This gives four total tides per day, roughly every six hours, though the exact times shift by about 50 minutes each day because a tidal day is about 24 hours 50 minutes. The heights of the two highs and the two lows can vary, but the count remains two highs and two lows, which is why this option fits best.
