PDE Q15
0. Tides in the oceans are caused by:
- Option : C
- Explanation :
-
A. Gravitational pull of the moon on the earth's surface including sea water
→ Partly correct, as the moon is the main cause of tides, but it ignores the sun’s role. -
B. Gravitational pull of the sun on the earth's surface only and not on the sea water
→ Incorrect, because the sun affects sea water too, and tides involve the oceans, not just land. -
C. Gravitational pull of the moon and the sun on the earth's surface including the sea water
→ Correct, as both the moon and sun’s gravity influence tides in the oceans. -
D. None of these
→ Incorrect, because option C is the correct explanation.
So, C is correct.
