Question:
The Earth’s equatorial and polar radius respectively are:
The Earth’s equatorial and polar radius respectively are:
Show Hint
Earth's equatorial radius>polar radius due to centrifugal bulging from rotation.
Updated On: May 21, 2025
- 6357 km and 6378 km
- 6378 km and 6357 km
- 3189 km and 3178.5 km
- 3178.5 km and 3189 km
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Earth is not a perfect sphere but an oblate spheroid, meaning it is flattened at the poles and bulged at the equator. Therefore:
- Equatorial radius = 6378 km
- Polar radius = 6357 km
- Equatorial radius = 6378 km
- Polar radius = 6357 km
