Question 1967Navigation General

The correct answer is B) Two. The East Coast of the United States experiences two high waters (or high tides) each day due to the semi-diurnal tidal pattern. This means that there are two high tides and two low tides approximately every 24 hours and 50 minutes. This is a result of the gravitational pull of the moon and the Earth's rotation. The other options are incorrect because A) One high water per day is not accurate for the East Coast, C) Three high waters per day does not occur naturally, and D) Four high waters per day is also not the typical tidal pattern observed along the East Coast of the United States.
