how frequently do most coastal areas experience high tides?\ntwice a day\ntwice a month\nfour times a…

Brief Explanations:

Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans. Most coastal areas experience two high tides and two low tides each lunar day (which is about 24 hours and 50 minutes). This is because as the Earth rotates, different parts of it pass through the areas of higher and lower gravitational pull from the moon (the main driver of tides).

Answer:

twice a day
