As the weather changes, plants change, too, and animals change their behavior to suit the weather. In spring, the weather begins to get warmer and trees and other plants grow new leaves.
Summer is the hottest season and has long, usually sunny, days. In the fall, the weather becomes mild and leaves start falling from many types of trees.
Winter is the coldest season, with short days. Many trees are bare and some animals enter a deep sleep called hibernation. They do this to save energy until spring, when it will be easier to find food.
This is why we have seasons. In most cultures, including all western countries, the year is commonly divided into four seasons:. Since the year has 12 months , each season lasts about three months. However, the dates when the seasons begin and end vary depending on whom you ask. Two methods are most commonly used to define the dates of the seasons: the astronomical definition and the meteorological definition.
The astronomical definition uses the dates of equinoxes and solstices to mark the beginning and end of the seasons:. What are equinoxes and solstices? Because the timings of the equinoxes and solstices change each year, the length of astronomical seasons within a year and between years also vary.
According to the meteorological definition, the seasons begin on the first day of the months that include the equinoxes and solstices.
