We divide up the year into four seasons: spring, summer, autumn, and winter. Each season lasts 3 months with summer being the warmest season, winter being the coldest, and spring and autumn lying in between. The seasons have a lot of impact on what happens on the earth. In the spring, animals are born and plants come back to life. Summer is warmer and is when kids are usually out of school and we go abroad on holidays. Often crops are harvested at the end of the summer. In autumn the leaves change colours and fall off the trees and school starts again. Winter is cold and it snows in many places. Some animals, like bears, hibernate in the winter while other animals, like birds, migrate to warmer climates.
