Consider the following statements:1. The axis of Earth's rotation is ...
1. Statement 1 is correct. The axis of Earth's rotation is indeed inclined at 23.5° to a perpendicular to the plane of the ecliptic. This inclination is significant as it causes the seasonal variations experienced on Earth.
2. Statement 2 is incorrect. The velocity of Earth's rotation is actually greatest at the equator and decreases towards the poles. This is because the equatorial region is the widest part of the Earth, and thus, points on the equator must travel a longer distance in the same period (24 hours) compared to points near the poles.
3. Statement 3 is incorrect. The weight of a body is less at the equator than at the poles. This is due to the greater centrifugal force experienced at the equator as a result of the higher rotational velocity, which effectively reduces the gravitational force felt by an object. Additionally, the Earth's equatorial bulge means the surface is farther from the center of gravity, slightly reducing gravitational pull as well.
Thus, only statement 1 is correct. Hence, the correct answer is Option A: 1 Only.

Consider the following statements:1. The axis of Earth's rotation is ...
Understanding the Statements
To evaluate the correctness of the statements about Earth's rotation and its effects, let’s analyze each one carefully.
Statement 1: Earth's Axis Inclination
- The Earth's axis is indeed inclined at approximately 23.5° from the perpendicular to the plane of the ecliptic.
- This tilt is responsible for the changing seasons as the Earth orbits around the Sun.
- This statement is correct.
Statement 2: Velocity of Earth's Rotation
- The velocity of Earth's rotation is not greatest at the poles; it is actually greatest at the equator.
- This is due to the larger circumference at the equator compared to the poles, where the rotational speed decreases to zero.
- This statement is incorrect.
Statement 3: Weight Variations
- The weight of a body is actually less at the equator compared to the poles.
- This is due to the centrifugal force experienced at the equator, which counteracts gravitational pull, making objects weigh slightly less.
- This statement is incorrect.
Conclusion
- Based on the analysis, only Statement 1 is correct.
- Therefore, the correct answer is option 'A' (1 Only).
This breakdown clarifies the misconceptions in the other statements while affirming the correctness of the first statement about Earth's axial tilt.
