Study Notes
Tides Overview
- Tides are influenced by the gravitational pulls of the sun and moon, creating cyclical patterns of high and low water levels in oceans and seas.
- The moon has the greatest influence on tides due to its proximity to Earth.
Spring Tides
- Occur when the sun, moon, and Earth are aligned, resulting in the highest high tides and lowest low tides.
- Occur during new and full moon phases.
Neap Tides
- Occur when the sun and moon are at right angles to each other, leading to the least difference between high and low tides.
- Occur during the first and third quarter moon phases.
Tidal Features
- High tide is characterized by a water bulge directly under the moon.
- Low tide occurs at locations between the bulges where the moon’s influence is weaker.
- The tidal range refers to the height difference between high and low tides.
Frequency and Patterns
- The number of tides can vary by location and is typically influenced by geographic features, such as coastlines and ocean floor shapes.
- Spring and neap tides generally occur twice a month, aligning with the lunar cycle.
Moon Phases and Timing
- It takes approximately one week for the moon to transition from new/full phases to quarter phases.
- The moon takes about two weeks to go from new moon to full moon.
- The moon completes a full revolution around Earth in about one month, while Earth’s revolution around the sun takes one year.
Practical Applications
- Understanding tidal patterns aids in planning beach activities like swimming, beachcombing, building sandcastles, and shelling.
