The month of September is marked by the beginning of spring and we could not fail to bring some physical explanations about the changes of seasons. Look that:

Earth Movements

Among the various movements that the Earth exerts, the Translation is mainly responsible for the changes between the four existing seasons: winter, spring, summer and autumn. Depending on the position of the Earth relative to the Sun, each region will have a greater or lesser incidence of sunlight, which makes us feel the climatic differences on the Earth’s surface.

Format and positioning of the Earth

Another fundamental factor for the changes of seasons is the fact that the Earth is spherical and have a slope of 23.5 degrees on its axis. In this way, the solar rays will reach different regions, at different intensities. It is because of this inclination that, for example, at the same time as it is summer in the southern hemisphere, it is winter in the northern hemisphere.
