Consider the following statements:
Statement-I: Melting polar ice caps due to climate change are causing the Earth to spin more slowly, leading to minute changes in the duration of a day.
Statement-II: The principle of angular momentum explains the slowdown in Earth's rotation, as polar ice melts and moves towards the equator, increasing the Earth's moment of inertia.
Which one of the following is correct in respect of the above statements?
- a)Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
- b)Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I
- c)Statement-I is correct, but Statement-II is incorrect
- d)Statement-I is incorrect, but Statement-II is correct
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Consider the following statements:Statement-I: Melting polar ice caps...
Both Statement-I and Statement-II are individually correct. Statement-I highlights the effect of melting polar ice caps on the Earth's rotation, causing a slowdown. Statement-II correctly mentions the principle of angular momentum and the Earth's moment of inertia but does not directly explain the specific relationship between the melting ice caps and the Earth's rotation slowdown. The slowdown in Earth's rotation due to melting ice caps is a result of complex interactions involving changes in mass distribution and conservation of angular momentum, which Statement-II does not explicitly elucidate.

Consider the following statements:Statement-I: Melting polar ice caps...
Overview of the Statements
The statements discuss the impact of melting polar ice caps on Earth's rotation, particularly in relation to angular momentum and moment of inertia.
Statement-I Analysis
- Melting polar ice caps do contribute to changes in the Earth's rotation.
- When ice melts, water moves from the poles towards the equator, which can lead to a slight increase in the duration of a day.
- This is due to the redistribution of mass on the planet, affecting its rotational speed.
Statement-II Analysis
- The principle of angular momentum states that if no external torque acts on an object, its angular momentum remains constant.
- As polar ice melts and shifts towards the equator, the Earth's moment of inertia increases, leading to a slowdown in its rotation.
- This change in moment of inertia results in a longer duration of a day due to the conservation of angular momentum.
Conclusion
- Both statements are correct: Statement-I accurately describes the phenomenon of increased day length due to melting ice caps, while Statement-II explains the underlying principle of angular momentum that accounts for this change.
- Therefore, the correct answer is option 'B': Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I.
Key Takeaways
- Melting ice caps impact Earth's rotation.
- Angular momentum conservation is crucial in understanding this effect.
- The correct interpretation of both statements reinforces the interconnectedness of climate change and Earth's physical dynamics.
