Seasonal Variability

Seasonal variability refers to the regular changes in weather patterns, temperatures, and other environmental factors that occur throughout the year due to Earth's tilt and orbit around the Sun. These variations cause seasons—spring, summer, fall, and winter—with distinct characteristics such as temperature shifts and changes in daylight. For example, summers tend to be warmer because the Sun's rays hit certain areas more directly, while winters are cooler when the Sun's rays are less direct. This cyclical pattern influences ecosystems, agriculture, and human activities, creating predictable, seasonal differences in the environment.
