Like all the planets in the Solar System, the Earth spins on its own axis and it also orbits the Sun . These two movements cause the difference between day and night and the changing of the seasons.
The Earth takes 365 days, 5 hours and 48 minutes to orbit the Sun. On 20 March and 21st September, days and nights are the same length – both 12 hours. This is called an equinox.
Every 4 years, the month of February has 29 days instead of 28. This is called a leap year.
The Earth is divided into 24 different time zones by imaginary lines that go from pole to pole. Each time zone is one hour different from its neighbours, with the Greenwich Meridian at the centre.
The Earth is divided into two halves: the northern and southern hemispheres. The equator is the imaginary line that separates the two hemispheres. When it is summer in the northern hemisphere, it is winter in the southen hemisphere
