Why
Isaac Newton worked out in 1687 that the near-side bulge is pulled toward the Moon, and the far-side bulge exists because the solid Earth is tugged away from the water.
The Frontline Impact
How this affects you
The gravitational interaction between the Earth and Moon causes tidal bulges on opposite sides of the planet, leading to the ocean tide rising twice a day. This interaction also results in the Moon slowly moving away from Earth at a rate of 3.8 centimeters per year.
