Frequently asked questions :
Where does the water go when it recedes?
In reality the water goes nowhere, it is the phenomenon of the attraction of the Moon and the Sun on the Earth and the centrifugal force which makes the water rise momentarily (as if it were magnetised, like a bulge) and as a result it is less spread out on the ground and the foreshore is exposed.
Why are there 2 tides a day ?
The first is due to the attraction of the Moon when it is aligned with the Sun. It attracts the oceans and thus creates the tide we know. The second is due to the fact that the Earth rotates and the centrifugal force creates a movement of the oceans identical to that of the attraction of the Moon but in the opposite direction.
How long does the sea rise or fall ?
The sea rises for 5 to 6 hours, remains stable for about 20 minutes, then falls again for another 5 to 6 hours.
