Question

Days are shorter in winter than in summer because:

• A. The earth' s axis is tilted.
• B. The sun is tilted.
• C. The climate results in shortening of days.
• D. None of the above

Answer 1

The correct option is A The earth' s axis is tilted.

Days are longer in summer and shorter in winter because the earth spins on its axis that is tilted.
As the earth revolves around the sun once per year, the angle at which the planet receives sunlight changes.
The tilted axis changes the position of the sun in the sky, making it appear for more or fewer hours, depending on the season and the latitude, or distance from the equator.
So, the correct option is A.
