A "season" refers to a division of the year marked by specific weather patterns and daylight hours. There are four main seasons: spring, summer, autumn, and winter. Each season has distinct characteristics, such as temperature changes and types of vegetation. Seasons are caused by the tilt of the Earth's axis as it orbits the sun. This tilt results in varying sunlight exposure in different regions, leading to seasonal changes. For example, during summer, days are longer and warmer, while winter brings shorter days and colder temperatures.
