Question

how often do spring and neap tides occur?
o twice a day
o twice a month
o every 27.3 days
o every 24 hours

Explanation:

Spring and neap tides occur due to the positions of the Sun and Moon relative to the Earth. Spring tides (higher high tides and lower low tides) and neap tides (lower high tides and higher low tides) happen when the Sun - Moon - Earth alignment is specific. The lunar cycle (about 29.5 days) and the relative positions of Sun and Moon lead to these tides occurring approximately twice a month.

Answer:

twice a month
