Study Notes
Earth's Relationship with Moon Phase (Spring and Neap Tides)
- The gravitational pull of the moon and sun on Earth's oceans causes tides.
- The moon's gravitational pull is stronger than the sun's, but the sun also plays a role.
- Spring tides occur during new moon and full moon phases.
- During these phases, the gravitational forces of the sun and moon align, strengthening each other's pull on Earth's oceans.
- This results in higher high tides and lower low tides than average.
- Neap tides occur during the first and third quarter moon phases.
- During these phases, the sun and moon pull at right angles to each other.
- This results in weaker combined gravitational forces, leading to less extreme tidal ranges (smaller differences between high and low tides).
- Students observe the cyclical patterns of spring and neap tides throughout a lunar cycle.
Time of Day (High Tide/Low Tide)
- Tides are not uniform throughout the day.
- They occur in cycles, with high and low tides approximately every 12 hours and 25 minutes.
- The time of high and low tides varies from place to place on Earth due to the shape of coastlines, ocean basins, and local topography.
- Specific coastal areas exhibit predictable patterns related to the time difference of high and low tide from the precise moon position over time.
- Students investigate data relating to specific locations, noting the correlation between tidal predictions and daily occurrences.
- Students recognize that the Earth's rotation on its axis and the moon's orbit around the Earth are key factors in determining the precise time of high and low tide at a given location.
