🔍 Key Concepts

• Difference between a solar day (based on the Sun) and a lunar day (based on the Moon) • The Moon’s eastward motion around the Earth each day • Relation between the time of successive high waters (high tides) on consecutive days

💭 Think About

• Think about how long it takes for a point on Earth to go from having the Moon directly overhead back to the Moon overhead again. Is that the same as a solar day? • If the Moon moves a little eastward each day, will the Earth have to rotate more or less than one full turn to bring the same point back under the Moon? What does that do to the length of the lunar day? • From one day to the next, does high tide tend to occur at roughly the same time, or noticeably earlier or later? By about how much?

✅ Before You Answer

• Recall that a solar day is 24 hours; compare this to the typical interval between successive high tides at the same location. • Estimate how many extra minutes it might take for Earth to “catch up” to the Moon’s new position after one solar day. • Be sure the option you choose matches the idea that a lunar/tidal day is tied to the Moon, not the Sun.
