Which two factors mainly affect ocean tides on Earth?

Check two answers.

Earth's revolution about both the Moon and the Sun

the Moon

the Sun

the pull of distant planets

The two factors that mainly affect ocean tides on Earth are:

1. The Moon: The gravitational attraction between the Moon and the Earth is the primary factor that causes tides. The Moon's gravitational pull on the Earth's water creates tidal bulges on opposite sides of the Earth, resulting in high tides.

2. The Sun: Although the Moon has a more significant impact on tides, the Sun also contributes to the tides. The gravitational force of the Sun also affects the Earth's water, causing additional tidal bulges. When the Sun, Moon, and Earth align, such as during a new moon or a full moon, it creates spring tides which are higher tides. When the Moon and Sun are at right angles to each other, such as during a quarter moon, it creates neap tides which are lower tides.

Therefore, the correct answers are "The Moon" and "the Sun." The other options, such as Earth's revolution about both the Moon and the Sun and the pull of distant planets, do have some influence on tides but are much less significant compared to the direct gravitational effects of the Moon and the Sun.
