Earth's tides. How the moons gravity and other factors affects this natural pattern.

Earth's Tides Gravity is the key to the Earth's rising and falling tides. The combined gravitational effects of the Sun and the Moon constantly pull the world's oceans in different directions and create tidal effects. But there are several other factors that complicate this basic process. Friction, the Earth's rotation, the tilt of its axis and the gravitational pull given off by the Sun and Moon that affects Earth's atmosphere. These forces together conspire to …showed first 75 words of 630 total…

This implies that ocean tides would be so enormous that they would regularly swamp many of the world's lowland regions at every high tide. The tidal force would also be strong enough to cause parts of the earth's crust to flex up and down with the tides resulting in catastrophic earthquakes.
