seasonal changes
Nature's quarterly transitions
Seasonal changes are the cyclical shifts in weather, temperature, daylight, and natural phenomena that occur as Earth orbits the sun throughout the year.
These changes mark the transitions between spring, summer, autumn, and winter, bringing predictable patterns like falling leaves, migrating birds, or lengthening days.
The phrase also applies to human activities tied to these cycles: Retailers prepare for seasonal changes in consumer spending.
In biology and ecology, seasonal changes trigger behaviors like hibernation, breeding, and plant dormancy.
