Question:
Which of the following statements is correct regarding Earth's dimensions?
Which of the following statements is correct regarding Earth's dimensions?
Show Hint
The Earth is an oblate spheroid.
\[
\boxed{
\text{Equatorial Diameter}>\text{Polar Diameter}
}
\]
This is due to the Earth's rotation.

- Polar diameter is greater than equatorial diameter
- Equatorial diameter is slightly greater than polar diameter
- Both diameters are exactly equal
- Polar diameter is double the equatorial diameter

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
The Earth is not a perfect sphere but an oblate spheroid, being slightly flattened at the poles and bulging at the equator due to its rotation.
Step 1: Recall Earth's dimensions. Approximate values are: \[ \text{Equatorial diameter} \approx 12756\ \text{km} \] \[ \text{Polar diameter} \approx 12714\ \text{km} \] Thus, \[ \text{Equatorial diameter}>\text{Polar diameter}. \]
Step 2: Identify the correct statement. Since the Earth bulges at the equator, \[ \boxed{\text{Equatorial diameter is slightly greater than polar diameter}.} \] Therefore, the correct option is \[ \boxed{(B).} \]
