Answer:
What were you suppose to do?
in the earth's atmosphere is made up about approximately 78 percent nitrogen and 21 percent oxygen.
Only some of the equator gets to experience day and night. When Uranus revolves around the Sun, one part gets light and day while the other gets night and darkness. So it changes because one time you can be looking and its day. Then you will look again and it will be night since Uranus moved around the Sun.
