Consider the following statements regarding the impact of climate cha...
1. Melting of polar ice caps increases the Earth's oblateness and moment of inertia: This statement is correct. The melting polar ice caps cause water to redistribute from the poles towards the equator, which increases the Earth's oblateness (flattening at the poles) and moment of inertia. This change in mass distribution affects the Earth's rotational dynamics.
2. The Earth's rotational axis shift due to melting ice can lead to significant changes in the duration of a day: This statement is incorrect. Although the melting ice causes a slight shift in the Earth's axis of rotation, it is not significant enough to cause major changes in the duration of a day. The duration changes are primarily due to the conservation of angular momentum as the mass distribution changes, which affects the rotational speed but not through axis shifts.
3. Variations in Earth's rotation can affect the accuracy of GPS systems: This statement is correct. GPS systems rely on precise time measurements, and any variations in Earth's rotation can impact the accuracy of these systems. Changes in rotational speed can introduce minor errors in navigation and location services.
Therefore, the correct answer is Option C
