If the earth were not tilted on its axis, what would be the result?
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 days.

 Days and nights would still occur since that is due to the earth's rotation. If the earth were not tilted on its axis, temperatures would be constant year round.

> If the Earth did not tilt on its axis, there will be no changing of seasons too. Temperatures at the north may stay cold and the south,warm..(no big change year round).
