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.
-
A.
1 only
-
B.
2 and 3 only
-
C.
1 and 3 only
-
D.
1, 2 and 3
Correct Answer:
D. 1, 2 and 3
Explanation:
Tides in the oceans and seas occur due to the combined effects of:
The gravitational force of the Sun,
The gravitational force of the Moon, and
The centrifugal force generated due to the Earth-Moon system's rotation around their common center of mass.
All three forces together cause the rise and fall of ocean water levels, leading to the tidal cycles experienced on Earth.
Therefore, the correct answer is (d) 1, 2 and 3.
