Final answer:
The statement suggesting there is one high and one low tide every 12 hours is false as there are typically two high tides and two low tides every 24 hours due to the Earth's rotation beneath the tidal bulges caused by the Moon's gravitational pull.
Step-by-step explanation:
The statement that tides occur about every 12 hours with one high and one low tide every day is false. In reality, most places on Earth experience two high tides and two low tides roughly every 24 hours due to the Earth's rotation underneath the tidal bulges caused by the gravitational pull of the Moon. The Earth rotates under these bulges in the Earth-Moon system, and as it rotates, any given point on Earth's surface passes through both tidal bulges each day, resulting in two high tides and two low tides.
Additionally, due to the Moon's orbit around Earth, the exact time between high tides and low tides is not precisely 12 hours, but about 12 hours and 25.2 minutes, which is why we do not have a perfect schedule of high and low tides at exactly 6-hour intervals.
Therefore, the correct option for the answer is false, as there are generally two high and low tides each day.
