Study Notes
Tides Overview
- Tides represent daily fluctuations in ocean water levels, influenced by gravitational forces.
Spring Tide
- Spring tides result in the highest high tides, occurring when the Earth, Moon, and Sun align in a straight line.
Neap Tide
- Neap tides exhibit the smallest difference between high and low tides, caused when the Sun, Earth, and Moon form a right angle (ninety degrees).
Influence of Lunar Phases
- Full and New Moons trigger spring tides due to their alignment.
- The 1st and 3rd Quarter Moons are responsible for neap tides.
Gravitational Forces
- The Moon's gravitational pull is crucial for creating Earth's tides.
Earth's Rotation
- Earth rotates on its axis approximately every 24 hours.
High and Low Tides
- High tide occurs when water levels rise above the average sea level.
- Low tide occurs when water levels drop below the average sea level.
Tidal Frequency
- Spring tides occur every 14 days, coinciding with the lunar cycle.
- The transition from low tide to high tide averages about 6 hours and 12.5 minutes.
Time Intervals
- The duration from one high tide to the next typically exceeds 12 hours.
Tidal Range
- The tidal range refers to the difference in height between the lowest and highest tides.
