If Earth were not tilted on its axis, what change would we experience?

A) Day length would be less than 24 hours.

B) Both sides of the moon would be visible.

C) Temperatures would be constant year round.

D) The length of the year would be more than 365

If Earth was not titled on its axis, Temperatures would remain constant year round, Option C.

Explanation:

Earth is tiled at 23.5 degrees. If it was not titled, there would no seasons, which means temperatures would not have changed around the year.

Earth has season because the axis on which it rotates is tilted at 23.5 degrees. The seasons occur as the tilted Earth travels in a loop around the Sun each year. When it is tilted 'towards' the sun, summer occurs in that hemisphere tilted. Winter season arrives when it gets tilted 'away' from the sun. This way different parts of Earth receive direct rays from sun. This is the reason days are longer during the summer as compared to during winters.
