What is Spring?
Spring is a season. There are four seasons in a year, spring, summer, autumn and winter. Each season is marked by different weather and hours of daylight.
We have seasons because the earth takes a year to move round the sun, which gives us light and warmth, and because the earth tilts at an angle of 23.5 degrees. In winter we tilt away from the sun and in the summer we tilt further towards the sun. However, on the first day of spring the sun shines equally on both the north and south hemispheres of the Earth.
