Rotation and Revolution
By: Bill Mitrousis
What is Revolution?
Revolution means that you are going to go around 1 time. For example, the Earth will revolve around the sun and it's going to take 1 year. It's January 1 and the earth is at the first side, 6 months later, it's at the other side now, another 6 months, it's at the first side that equals 1 year.
Day and Night
Day is important because we need heat and light from the sun and stay alive. If the first halve is facing the sun, it's day. If it not it's night. For example, day is 7:00 AM-6:00 PM, and night is 6:00 PM- 7:00 AM. At night we could see the beautiful stars and the shiny moon, night could be important like day.
