Q. Consider the following statements:

1. As we go northwards in northern hemisphere in winter, the hours of sunlight increase.
2. Dawn and twilight period in temperate latitudes is longer than in tropical latitudes.

Which of the statements given above is/are correct?
Answer: Only 1
Notes: The Earth's axis is tilted at 66.5 degrees to the ecliptic, causing seasonal variations and differing day lengths. In the northern hemisphere, winter brings increasing darkness northward, while summer sees longer daylight. Dawn is the time from sunrise to full daylight, and twilight is from sunset to darkness. At the equator, the sun rises and sets vertically, resulting in shorter periods of refracted light, whereas in temperate regions, the oblique path of the sun extends these periods.
