Question

why are the days sometimes longer sometimes shorter ?

Answer 1

Explanation:

• In summer days are longer but nights are shorter.
• In winter nights are longer but days are shorter.
• This is because of sun light.

Answer 2

Answer:

This phenomenon occurs because the Earth's axis is not straight up and down at a 90 degree angle, but it is instead tilted a bit. Therefore, as the planet orbits the sun every 365 days, sometimes the Northern hemisphere is closer to the sun (summer) while sometimes it is farther away (winter).
