Which is the cause of tropic tides?
• Declination of the Moon and how far north/south of the equator it is • Difference between equinox conditions (near 0° declination) and when a body is far from the equator • How extreme declinations affect the range of tide
• Which choice describes the Moon’s position when it is farthest north or south of the equator? • How would the Moon being high above the northern or southern hemisphere (in declination) change the tidal range compared to when it is over the equator? • Which option seems related to ‘tropic’ as in Tropic of Cancer/Capricorn rather than ‘equatorial’ or ‘perigee’?:
• Identify which options refer to 0° declination / equator versus large declination • Separate ideas of distance from Earth (perigee) from angular position (declination) • Match the word tropic with positions related to the Tropics (high declination) rather than the equator
