árstíðum

Árstíðir, commonly known as seasons, are divisions of the year marked by particular weather patterns and daylight levels. In many temperate regions, there are typically four distinct seasons: spring, summer, autumn (or fall), and winter. These cycles are primarily driven by the Earth's axial tilt and its orbit around the Sun.

Spring is characterized by increasing temperatures, longer days, and the regrowth of vegetation after winter. Many plants bloom, and animals often emerge from hibernation or return from migratory journeys.

Summer is the warmest season, with the longest days of the year. It is often associated with outdoor activities and peak agricultural production.

Autumn witnesses a gradual decrease in temperatures and daylight. Leaves on deciduous trees change color and fall, and many animals prepare for winter through migration or by storing food.

Winter is the coldest season, with the shortest days. Snow and ice are common in many areas, and some animal species hibernate.

The timing and intensity of these seasons can vary significantly based on geographical location, with tropical regions experiencing less distinct seasonal changes and polar regions having very prolonged periods of light and darkness. The alternation of seasons has profoundly influenced human cultures, agriculture, and traditions throughout history.
