Is the time of day due to earths rotation or revolution?

seriuosly?!!!

This is a really dumb question, think about it for 2 seconds, go on try it!







OK, well I hope you got it all by yourself, but in case you didn't: when your side of the earth is pointing towards the sun it's daytime right. But oh no! the Earth rotates! So after only a few hours your side of the Earth will now be pointing away from the Sun. Shazam! It's nighttime!
