The seasonal cycle refers to the annual pattern of changes in climate and daylight that occur due to the tilt of the Earth's axis and its orbit around the Sun. This cycle typically includes four distinct seasons: spring, summer, autumn, and winter. Each season has unique weather characteristics, such as temperature and precipitation, influenced by the position of the Earth relative to the Sun. As the Earth orbits the Sun, different regions receive varying amounts of sunlight throughout the year. This variation leads to changes in plant growth, animal behavior, and human activities. For example, many plants bloom in spring, while animals may hibernate during winter. The seasonal cycle plays a crucial role in ecosystems and agriculture.
