Seasons

The Earth's axis is tilted relative to its orbit around the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing of seasons.

Causes of Seasons

Seasons are caused by the tilt of the Earth's axis and its orbit around the Sun. When a particular hemisphere is tilted towards the Sun, it experiences summer, while the hemisphere tilted away from the Sun experiences winter. As the Earth orbits the Sun, the tilt causes the Sun's rays to strike different parts of the Earth at different angles, leading to variations in temperature and climate.

Types of Seasons

There are four main seasons: spring, summer, autumn (fall), and winter. These seasons are characterized by specific weather patterns, temperatures, and the length of daylight. Each season has its own unique features and impacts on the environment and living organisms.

Impact of Seasons

Seasons play a crucial role in shaping ecosystems, influencing plant growth, animal behavior, and agricultural activities. They also impact human activities, such as outdoor recreation, clothing choices, and energy consumption.
