Where does seawater go when it’s low tide?
In: Physics
Think of the sea as a ferofluid that’s wrapped round a big magnet (earth) and is also being very slightly pulled by another magnet really far away (the moon).
It will always slightly bulge towards the far away magnet. When the moon is close the sea is high, when it isn’t the moon far away.
The tide is like a sloshing back and forth because of this moving pull, like when you sit in the bath and cause ripples.
But instead you’re a planet and moon ans the bath is the sea, so the sloshing is the tide
