What causes day and night?
The Earth rotates on its axis every 24 hours.  When we are facing the sun, it is daytime and when we are not, it is night. 

How does the Earth move in our solar system?
The Earth takes 365 and a quarter days to revolve around the sun.  It travels on the same path every year.  This is called its orbit.
