Question

5. During a waxing gibbous moon, we can expect to see which type of tides?
6. How often does the Earth experience Spring and Neap tides?

Answer 1

5. A waxing gibbous is between first quarter and full moon, so tides are moving toward a spring tide. You’ll see an increasing tidal range (larger-than-average tides) as the Moon approaches full — the actual peak spring tides occur at full (and new) moon.

6. Spring tides occur twice each lunar month (at new and full moon) — about every 14.8 days between successive spring tides. Neap tides also occur twice each lunar month (at the first and third quarters), with the spring↔neap cycle changing roughly every 7.4 days.
