When the tide comes in on a beach, where does the extra water come from?

572 views

Logically I understand that a.) the ocean is HUGE so the amount of incoming water is infitismally tiny compared to the whole, and b.) it is one large body so when the tide comes in there are other beaches where the tides goes out; but are there any other factors to this? Does gravity affect the mass/density of the water somehow that can also attribute to the change?

Think of the oceans as a giant water bed, you put something heavy on one end and it pushes the opposite end up.
In the case of the ocean it’s actually a pulling action by the moons gravity that causes the water to swell.
