Is the red sea only place tide ebbs and flows twice in 24 hours?

The statement that the Red Sea is the only place where the tide ebbs and flows twice in 24 hours is not accurate. Tides are a result of the gravitational pull of the moon and the sun on the Earth's oceans. The Earth rotates on its axis once every 24 hours, so most locations experience two high tides and two low tides per day. The exact timing and amplitude of these tides depend on the location's latitude, longitude, and local topography.

While the Red Sea does experience tides, they are not unique in having two high tides and two low tides daily. Other locations worldwide also have semi-diurnal tides, including much of the Atlantic and Pacific Oceans.
