Tides occur in the oceans and seas due to which among the following?

1. Gravitational force of the Sun
2. Gravitational force of the Moon
3. Centrifugal force of the Earth

Select the correct answer using the code given below:

1. 1 only
2. 2 and 3 only
3. 1 and 3 only
4. 1, 2 and 3

Explanation

All Options are correct

• Tides in oceans and seas are caused by the combined effects of the gravitational forces of the Moon and the Sun, along with the centrifugal force produced by the Earth–Moon system. The Moon’s gravitational pull is the primary factor responsible for tides due to its proximity to Earth, while the Sun’s gravitational force also contributes, leading to spring and neap tides.
• Additionally, the centrifugal force generated by the rotation of the Earth–Moon system creates a second tidal bulge on the opposite side of the Earth.
