🔍 Key Concepts

• Lunar nodal period and its relationship to the Moon’s orbit around Earth • Difference between daily/weekly tidal variations and long-term tidal modulation • How long-term cycles (like those used in tidal prediction tables) are typically measured (days vs. years)

💭 Think About

• Think about whether a cycle that significantly changes tidal characteristics would be something you notice over days, months, or many years. • Compare the scale of the nodal period to other known lunar and tidal cycles, such as the 28-day lunar month and the roughly 18- to 19-year cycles used in advanced tidal analysis. • Ask yourself: would a navigator or hydrographer track the nodal cycle in short-term planning (days) or in long-term tidal prediction (years)?

✅ Before You Answer

• Be sure you are distinguishing between the lunar month (~27–29 days) and much longer orbital cycles. • Confirm whether the nodal cycle is associated with orbital inclination/precession (long-term) or just the Moon’s phase cycle (short-term). • Eliminate options that are clearly on the wrong time scale for a major, named astronomical cycle affecting global tides.
