Key Points
- The gravitational attraction between the Earth, the Moon, and the Sun causes tides in the Earth's oceans.
- There are typically two high tides and two low tides in most locations around the world in a 24-hour period, resulting in a semi-diurnal tide pattern.
- Each high tide is followed by a low tide, and then there's another high tide and low tide.
- The time between successive high tides (or low tides) is approximately 12 hours and 25 minutes, which means there are about two high tides and two low tides in a day.
- This is because the Moon's gravitational pull causes a bulge of water on the side of the Earth facing the Moon (the high tide), and another bulge on the opposite side of the Earth (the low tide).
- The Sun's gravitational pull also contributes to the tides, though its effect is about half that of the Moon's due to the Sun's greater distance.
