1. The Moon's Gravitational Pull: The Moon's gravitational pull attracts the water on Earth, creating a bulge of water on the side of the Earth facing the Moon. This is the high tide.
2. The Centrifugal Force: The Earth and Moon are also rotating around their shared center of mass. This rotation creates a centrifugal force, pushing water away from the Earth's center. This force also contributes to a bulge of water on the side of the Earth opposite the Moon, creating another high tide.
3. Low Tides: Between the two high tide bulges, the water level falls, resulting in low tides.
4. The Sun's Influence: The Sun also has a gravitational pull on Earth's water, but it's weaker than the Moon's. When the Sun and Moon are aligned (during a new moon or full moon), their gravitational pulls combine, resulting in stronger tides called spring tides. When the Sun and Moon are at right angles to each other (during a quarter moon), their gravitational pulls partially cancel each other out, resulting in weaker tides called neap tides.
5. Wave Formation: Tides are not waves in the traditional sense. They are the rise and fall of water levels. However, the tides can create waves as they move across the ocean floor. These waves can be amplified by factors like wind and the shape of the coastline.
In short, the Moon's gravity pulls the water on Earth, creating bulges of water that result in high tides. The rotation of the Earth and Moon creates a centrifugal force that contributes to the second high tide. Between the high tides, the water level falls, resulting in low tides.
