So the first thing you should know is that as the Earth spins the water around the Earth stays at a steady level. This is because Earth’s gravity pulls inward and the centrifugal force pushing outward that is how the water stays in place but the Moon’s gravity is strong enough to disrupt the steady ocean levels by pulling water towards the Moon this causes a bulge of water on one side of the planet. As the Earth rotates and the Moon orbits the bulge of water moves. Those are the basics about how everything works. The high tides is where the bulge is and the low
