Why do we have season? well a lot of people think it is because the earth is closer to the sun but through science, we have discovered that’s not the reason at all. The reason is pretty simple. The earth is tilted. It takes earth one whole year to travel around the sun. But the tilt on June, September, March, December, the tilt stays the same as the Earth travels around the sun throughout the year.
So how do we have seasons
The changing seasons are due to the axial tilt of the Earth. The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the sun. This means that as the Earth revolves around the sun, different parts of the planet receive varying amounts of sunlight throughout the year, leading to the seasons.
During summer, the hemisphere tilted towards the sun receives more direct sunlight, leading to longer and warmer days. In contrast, during winter, the hemisphere tilted away from the sun receives less direct sunlight, resulting in shorter and colder days.
The equinoxes, which occur in March and September, mark the times when the tilt of the Earth's axis is perpendicular to the sun's rays. This means that the sunlight is evenly distributed between the northern and southern hemispheres, resulting in equal day and night durations.
In summary, it is the Earth's axial tilt and its revolution around the sun that causes the changing seasons.
