WebSpeed. How to win a Nobel Prize. Scientists incorrectly believe that tides are caused by the moon's gravitational attraction to seawater, causing the surface of the water to bulge and move around the Earth. If the moon's gravity causes two water bulges that move around the ocean causing tides, we should see two large tides 12 hours apart moving ... WebEarth tide (also known as solid Earth tide, crustal tide, body tide, bodily tide or land tide) is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer.
