Periodically on Earth

The change of seasons is a natural phenomenon that occurs periodically on Earth. This process involves changes in weather, temperature, and other natural patterns related to the Earth's position relative to the Sun in its orbit. This change in seasons is caused by the tilt of the Earth's axis and the Earth's elliptical orbit around the Sun. The tilt of the Earth's axis makes some parts of the Earth tilt more towards the Sun at certain times of the year, resulting in variations in the intensity of sunlight received, and ultimately affecting the weather and temperature on the Earth's surface. The phenomenon of changing seasons is not the same throughout the world. In some tropical and subtropical regions, there are only two main seasons, namely the rainy season and the dry season. Knowledge of seasonal changes is important for many aspects of human life, including agriculture, culture, and health, because seasonal changes affect human activities and the ecosystem as a whole.
