Study Notes
Earth's Tides
- Tides are daily changes in ocean water level due to gravitational forces from the sun and moon.
- Tidal force is the difference in gravitational pull between one side of Earth and the other.
- The moon's closer proximity to Earth results in a stronger tidal force compared to the sun's.
- The moon is the primary driver of tides on Earth.
High Tide vs Low Tide
- High tide is when the water level is higher than average sea level.
- Low tide is when the water level is lower than average sea level.
- Tidal bulges occur on both sides of Earth facing and opposite to the moon.
- As Earth rotates, locations experience high and low tides.
- Most locations experience two high tides and two low tides each day.
Tidal Ranges
- Tidal range is the difference between high and low tide levels.
- The tidal range varies depending on the positions of the sun and moon relative to Earth.
- Spring tides have a larger tidal range, occurring when the sun, moon and Earth are aligned.
- Neap tides have a smaller tidal range, occurring when the sun, moon and Earth form a 90-degree angle.
Timing of Tides
- Earth's rotation and the moon's orbit cause predictable tide cycles.
- A location facing the moon experiences high tide, while the opposite side experiences a high tide simultaneously.
- Each tide cycle takes approximately 24 hours and 50 minutes.
- The timing of tides varies slightly from location to location.
Specific Tide Examples (from provided data)
- June 3rd High Tide: 6:04 AM, Height 6.11m, Low Tide: 12:01 AM, Height 1.76m
- June 11th High Tide: 12:32 PM, Height 6.47m, Low Tide: 6:30 AM, Height 0.78m
