• WHAT ARE TIDES AND HOW DO THEY WORK? The Moon and its gravitational pull cause both high and low tides. As the Earth rotates, the Moon’s gravity pulls on different parts of the planet, even the land in very small amounts. While the Moon cannot easily pull the land of the Earth, water has a much easier time moving around and is naturally drawn in the direction of the Moon, causing water to “bulge out” on the sides of the Earth that are closest to and furthest from the Moon. This is called the tidal force, and those opposite “bulges” of water are high tides.
• Tides are one of the most reliable phenomena in the world. As the sun rises in the east and the stars come out at night, we know that ocean waters will regularly rise and fall along our shores.
