A day on Earth is approximately 24 hours, which is the amount of time it takes for Earth to complete

one rotation around its axis. How do the two tidal bulges created by the Moon align with the

number and frequency of tides for each coastal city analyzed in Task 1?

Because the Earth rotates through two tidal "bulges" every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
