Question 1 of 27070

Q

The period of revolution of the Moon is __________.

🔍 Key Concepts

• Difference between the Moon’s rotation on its axis and its revolution around Earth • Typical month-length used in astronomy and navigation (sidereal vs synodic month) • Scale of time for orbital periods vs daily or yearly cycles

💭 Think About

• Is the Moon’s path around Earth tied more closely to a day, a month, a year, or many years? • Which of the options is commonly associated with the length of a lunar month used in tide and navigation calculations? • Do very long cycles like 19 years describe a single orbit, or are they more likely to describe patterns made from many orbits?

✅ Before You Answer

• Be clear on the definition: revolution = one complete orbit around Earth • Compare each choice to what you know about the approximate length of a month • Ask whether any option is actually related to a different lunar cycle (e.g., nodal or eclipse cycles) rather than a single revolution
