Earth

 **Earth** Earth is the planet we live on, third from the Sun and the only planet known to support life such as animals, plants and trees.

Earth orbits the sun, once every 365 and a quarter days, otherwise know as a year. Whilst doing this the Earth also spins on its own axis, once every 24 hours which causes only half of the Earth to be facing the Sun at one time. This is the simple reason why there is day and night on Earth. The half of Earth where it is day is the side that is receiving light from the Sun. The half of Earth where it is night is the side that isn't receiving light from the Sun. See diagram below:    **Home**
