The moon’s gravity pulling on water causes the tides.

Well, it’s half true. On the side of the Earth facing the moon, the moon’s gravity does actually pull water toward it, causing the tides. On the other side, gravity is weaker and it’s the inertia of water from the Earth’s rotations that we have to thank. The fact that we’re spinning at about 1,040 mph causes the ocean water to fling into a slight bulge, which we call the tide.
