    It must be more complicated than just the pull of the moon, because at the same time on the opposite side of the earth, there is also a high tide.

      The explanation I'd seen previously involved force vectors, and the earth pulling away from the far-side bulge. I like your explanation better -- it is easier to grasp.

        could be that too, though if the Earth were being pulled closer to the Moon, the Earth's gravity would make the water follow it. If the Earth were being pulled out of round slightly then the tide wouldn't be higher as the ground would also be proportionally higher. I got the explanation I found from NOAA's website

          Funny. It was prolly why cant it pick up AFTER my dog. Cause, you know poop JR
