2 TidesThe daily rise and fall of Earth’s water on its coastlines is called a tide.Caused by the interaction of Earth, the moon and the sun.Tidal range is the difference in ocean level between high-tide and low-tide.
3 Gravitational Effect of the Moon Two big bulges (Tidal) of water form on the Earth:one directly under the moon (due to gravity)another on the exact opposite side (due to inertia)As the Earth spins, the bulges follow the moon.
4 The Daily Tide CycleOne low-tide and high-tide cycle takes about 12 hours and 25 minutes.

15 Tidal Energy – The Energy from Tides Clean, renewable source of energy.Harnessing tidal energy only possible when tidal range is at least 4 or 5 meters.Very few locations are suitable for tidal power plants.
