Question

Why do tides have a regular cycle of 12 hours even though the Moon completes one revolution of the Earth every 29.5 days?

(HELP PLEASE!!)

A. The Earth is rotating and completes a rotation every 24 hours. As it rotates, its distance from the Moon changes every 12 hours. This causes the cycle of high and low tide.


B. The Earth is rotating and completes a rotation every 24 hours. The moon also rotates as it resolves around Earth, which causes the cycle of high and low tide.


C. The Earth is rotating and completes a rotation every 24 hours. This means that the side of the Earth far from the Moon will be near the Moon 12 hours later, restarting the cycle of high and low tide.


D. The Earth is rotating and completes a rotation every 24 hours. This causes day and night to occur. High tide only occurs during the evening, and low tide only occurs during the day.

Answer 1

A. The Earth is rotating and completes a rotation every 24 hours. As it rotates, its distance from the Moon changes every 12 hours. This causes the cycle of high and low tide.

The regular cycle of tides is primarily caused by the gravitational interaction between the Earth and the Moon. As the Earth rotates on its axis every 24 hours, different parts of the Earth's surface come into closer proximity to the Moon. This changing distance between the Earth and the Moon results in the cycle of high and low tides occurring approximately every 12 hours.

The gravitational force exerted by the Moon on the Earth's oceans causes a tidal bulge to form on the side of the Earth closest to the Moon, resulting in high tide. Simultaneously, there is another high tide on the side of the Earth opposite the Moon due to the centrifugal force generated by the Earth-Moon system. These tidal bulges create the cycle of high and low tides as the Earth rotates.

It's important to note that while the Moon completes one revolution around the Earth every 29.5 days, the regular cycle of tides is primarily influenced by the Earth's rotation and the changing distance between the Earth and the Moon every 12 hours.

Answer 2

D

Step-by-step explanation:

The Earth is rotating and completes a rotation every 24 hours. This causes day and night to occur. High tide only occurs during the evening, and low tide only occurs during the day.
