Select an option to attempt

Explanation

Earth’s rotation and axis can shift due to changes in how mass is distributed across the planet, such as melting polar ice.

Statement I is correct:

  • Studies show that Earth’s rotation and axis are shifting slightly due to internal mass redistribution.

Statement II is correct:

  • But it doesn’t explain the shift — solar flares affect only the upper atmosphere, not Earth’s rotation.

Statement III is correct:

  • It explains the shift — melting polar ice moves water toward the equator, altering Earth’s mass distribution and spin.
