Understanding the Pairs
To determine how many of the given pairs are correctly matched, let's analyze each one:
1. Rotation of Earth
- Statement: Earth rotates from east to west.
- Analysis: This statement is incorrect. Earth rotates from west to east, leading to the rise of the sun in the east.
2. Inclination of Earth's Axis
- Statement: Earth's axis is inclined at 23.5° to the plane of the elliptic.
- Analysis: This statement is correct. The tilt of 23.5° is responsible for the seasons on Earth.
3. Velocity of Earth's Rotation
- Statement: Velocity is highest at the poles and decreases towards the equator.
- Analysis: This statement is incorrect. The rotational velocity is highest at the equator and decreases as you move towards the poles.
4. Polestar
- Statement: The brightest star in the North direction.
- Analysis: This statement is partially correct. Polaris, the North Star, is the brightest star in the northern celestial hemisphere, but "the brightest star in the North direction" may refer to its visibility rather than its brightness compared to other stars.
Conclusion
- Only the second pair regarding the inclination of Earth's axis is correctly matched. The first, third, and fourth pairs contain inaccuracies.
- Therefore, the correct answer is a) Only one pair.

Consider the following pairs:1. Rotation of Earth - Earth rotates fro...
1. Rotation of Earth - Incorrect. The Earth rotates from west to east, not east to west. This rotation is responsible for the apparent daily motion of the sun across the sky.
2. Inclination of Earth's Axis - Correct. The Earth's axis is inclined at 23.5° to the perpendicular to the plane of the elliptic. This inclination causes the variation in solar intensity experienced in different parts of the world, leading to seasons.
3. Velocity of Earth's Rotation - Incorrect. The velocity of Earth's rotation is highest at the equator and decreases towards the poles. This is due to the greater circumference at the equator compared to the poles.
4. Polestar - Incorrect. The Polestar, or Polaris, is not the brightest star in the sky, but it is the brightest star in the constellation Ursa Minor and is located nearly at the north celestial pole, making it an important navigational star in the northern hemisphere.
Hence, only pair 2 is correctly matched.
