Tides occur in 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
Explanation
Statement 1 is Correct: The Sun's gravitational pull contributes to tide generation. Although the Sun is significantly more massive than the Moon, its immense distance from Earth results in a tidal-generating force that is approximately 46% as strong as the Moon's.
Statement 2 is Correct: The Moon's gravitational pull is the primary force responsible for tides. It exerts a stronger pull on the side of the Earth facing it, drawing ocean water toward it and creating a tidal bulge.
Statement 3 is Correct: Tides are also influenced by centrifugal force, which arises from the revolution of the Earth and Moon around their common center of mass (the barycenter). This force acts in the opposite direction to the Moon's gravitational pull; on the side of the Earth facing away from the Moon, the centrifugal force exceeds the Moon's weakened gravitational pull, creating a second tidal bulge.
