Question

1. a high tide occurred at 6:00 a.m. at a beach on long island. the next high tide at this same beach would occur at approximately

a) 6:30 p.m. on the same day
b) 12:15 p.m. on the same day
c) 7:00 a.m. on the following day
d) 12:45 p.m. on the following day

Explanation:

Tides are caused by the gravitational pull of the Moon and the Sun on the Earth's oceans. The time between two high tides is approximately 12 hours and 25 minutes. If a high tide occurs at 6:00 a.m., adding 12 hours and 25 minutes to 6:00 a.m. gives 6:25 p.m. on the same day. But since the options don't have 6:25 p.m., we consider the fact that the lunar cycle affects the tides and the slight variation. Another way is to know that the tidal period is about 12 hours 25 minutes. 6 a.m. + 12 hours 30 minutes (approximate) is 6:30 p.m.

Answer:

A. 6:30 p.m. on the same day
