Introduction:

Seasons are a natural phenomenon that occurs due to the tilt of the Earth's axis. The Earth completes one revolution around the Sun in approximately 365.25 days, causing the change in seasons. There are four main seasons: spring, summer, autumn, and winter. Each season has distinct characteristics and lasts for a specific period of time.

Spring:
- Spring is the season that follows winter and precedes summer.
- It usually begins around March and lasts until June in the Northern Hemisphere.
- During spring, the Earth is tilted towards the Sun, resulting in longer and warmer days.
- The temperatures gradually rise, and plants start to bloom and grow.
- Spring is often associated with rejuvenation, as animals come out of hibernation and birds migrate back to their breeding grounds.

Summer:
- Summer is the hottest season of the year and follows spring.
- It typically starts in June and ends in September in the Northern Hemisphere.
- During summer, the Earth is tilted directly towards the Sun, resulting in the longest days and the highest temperatures.
- This season is characterized by clear skies, high temperatures, and the growth of crops.
- People often engage in outdoor activities and enjoy vacations during this time.

Autumn:
- Autumn, also known as fall, is the season that follows summer and precedes winter.
- It usually begins in September and lasts until December in the Northern Hemisphere.
- During autumn, the Earth's tilt starts to move away from the Sun, resulting in shorter days and cooler temperatures.
- The leaves on trees change color and fall off, creating a beautiful display of red, orange, and yellow hues.
- Harvesting of crops and preparations for the upcoming winter are common activities during this season.

Winter:
- Winter is the coldest season of the year and follows autumn.
- It typically starts in December and ends in March in the Northern Hemisphere.
- During winter, the Earth is tilted away from the Sun, resulting in shorter days and lower temperatures.
- This season is characterized by snowfall, freezing temperatures, and dormant vegetation.
- Many animals hibernate or migrate to warmer regions during this time.

Conclusion:
The change in seasons is a natural occurrence driven by the Earth's tilt and its revolution around the Sun. Each season has its own unique characteristics and duration. Understanding the seasons helps us adapt to the changing weather patterns and appreciate the beauty and diversity of nature.
