Question

why there are two high tide and two low tides a day?​

Answer 1

Answer:

Coastal areas experience two low tides and two high tides every lunar day, or 24 hours and 50 minutes. The two tidal bulges caused by inertia and gravity will rotate around the Earth as the moons position changes. These bulges represent high tides while the flat sides indicate low tides.

Answer 2

Explanation:

this occurs because the moon revolves around the earth in the same direction, that the earth rotates around it's axis because the earth rotates through the two tidal bulges every lunar day coastal areas experience two high and two low tide every 24 hours and 50 minutes and high tide occurs 12 hours and 25 minute apart..
