Seasons

The changing of seasons is a natural phenomenon that occurs due to the Earth's tilt on its axis as it orbits the Sun. There are four distinct seasons: spring, summer, autumn, and winter.

Causes of Seasons

The Earth's axis is tilted at an angle of approximately 23.5 degrees. As the Earth orbits the Sun, different parts of the planet receive varying amounts of sunlight, leading to the changes in seasons. When a particular hemisphere is tilted towards the Sun, it experiences summer, while the hemisphere tilted away from the Sun experiences winter.

Effects of Seasons

Each season brings about different weather patterns, temperatures, and lengths of daylight. Spring is characterized by blooming flowers and warmer weather, while summer is known for its long days and high temperatures. Autumn, or fall, sees the leaves changing colors and cooler temperatures. Winter brings cold weather, shorter days, and sometimes snow and ice.
