Why does the Moon affect the tides more than the Sun?

• The Moon is larger than the Sun.

• The Moon is closer to Earth than the Sun.

• The Moon has a lower gravitational effect than the Sun.

• The Moon has a lower temperature than the Sun.

The Earth revolves around the Sun due to the gravitational attraction between Sun and Earth. How would the Earth move if suddenly there was no gravitational attraction between the Earth and the Sun?

• Earth would continue to move in its same orbital path because of its inertia.

• Earth would stop moving without the Sun's gravitational pull.

• Earth would reverse its path because the Sun's gravity would no longer pull Earth toward it.

• Earth would move in a straight line because there would be no gravity to oppose its inertia.
