Consider the following statements: 1. During equinox, days and nights...
Explanation:
Statement 1: During equinox, days and nights are equal throughout the world.
During the equinox, the tilt of the Earth's axis is such that the Sun is directly above the equator. This means that the length of day and night is roughly equal all over the world. The equinox occurs twice a year, in March (spring equinox) and September (autumn equinox).
Statement 2: During the equinox, a circle of illumination cuts through the poles.
The circle of illumination is the boundary between the illuminated hemisphere and the dark hemisphere on the Earth's surface. During the equinox, the circle of illumination divides the Earth into two equal halves, with one half in daylight and the other half in darkness. This circle does not cut through the poles; instead, it passes through the points on the Earth's surface that are closest to the Sun.
Combining the statements:
Both statements are correct. During the equinox, the days and nights are equal throughout the world because the Sun is directly above the equator. The circle of illumination cuts through the points on the Earth's surface that are closest to the Sun, dividing the Earth into two equal halves. However, it does not cut through the poles.
Therefore, the correct answer is option C, i.e., both statements 1 and 2 are correct.

Consider the following statements: 1. During equinox, days and nights...
- During the equinox, the Sun is overhead at the equator, making days and nights equal throughout the world.
- Since the circle of illumination is the line that divides days and nights, it will cut through the poles during the equinox as poles are not inclined towards the Sun during this time.
