The term "seasonal cycle" refers to the natural and regular changes in weather patterns, temperature, precipitation, and daylight that occur over a period of time. These cycles are influenced by Earth's tilt on its axis and orbit around the sun, leading to seasonal variations such as winter, spring, summer, and fall. The length of each season varies depending on geographic location and climate conditions. Seasonal cycles also include changes in plant growth, animal behavior, and other natural phenomena that are influenced by these weather patterns.
