Why are there seasons of the year on our planet

Practically since the human being began to step on the Earth he felt the need to control the time to take advantage of the conditions of nature. Within this, the different periods through which the Earth passed throughout a year, was a fundamental element for know the migrations of animals and the appearance of the fruits of the trees, elements that were and are our source of food. In this lesson from a TEACHER we talk about why are there seasons of the year on our planet.

We begin the lesson on why there are seasons of the year on our planet, focusing on the definition of it. We can say that the seasons of the year are time spaces that are well differentiated from each other, where the climatic conditions are different. Each season of the year, usually last about 3 months approximately and are known by the names of autumn, winter, spring and summer.

Causes of the seasons of the year

Once we have defined what the seasons of the year are, we must talk about why they exist. This question has an easy answer and we have to look for it in the Sun.

As we know, the Earth revolves around the Sun, a movement that ends in 365 days; This means that, during its movement, the Earth passes through different distances from the Sun Throughout the months, making the Sun less distant in one period and further away at other times.

Depending on this, we will find that the different seasons of the year are made up.

Within the lesson we will talk a little about the various seasons our planet passes through over time. They are as follows:

• Fall: this occurs between the months of September and November in the northern hemisphere, while for the southern hemisphere the months of said season are from March to May. During this period we will find a considerable drop in temperatures, in addition to being the time in which the leaves of the trees usually fall, in the same way, it is a temporary space in which the rainfall.
• Winter: for the southern hemisphere it corresponds to the months of June to August and for the north to the months of December to February. This period is usually represented with very low temperatures and in places outside the tropics, it usually snows.
• Spring: in the northern hemisphere it corresponds to the months of March to May and in the south to the months of September to November. It is the time of year in which everything begins to bloom, thanks to the increase in temperatures, in the same way, during said months it is common to intersperse times of rainfall with dry days, which makes the planet recompose itself from the hard winter.
• Summer: in the southern hemisphere it corresponds to the months of December to February, while in the northern hemisphere it is the months of June to August. It coincides with the hottest time of the year, where we will find a significant number of droughts, although within this season it is also common to find the called summer storms, which discharge a large amount of water, undoubtedly due to the fact that when it is so hot the clouds are loaded with large amounts of steam of water.

In this other lesson we discover you where the sun rises and where it sets so that you know better how the universe works.

To conclude with the lesson on why there are seasons of the year on our planet, we want to answer this question. According to the latest studies carried out by astronomers over the last decades, it has been possible to know that there are more planets in our solar system that could have "seasons of the year."

This is because some planets, such as Saturn, Uranus or Mars, have a tilt and rotate axis similar to that of the Earth. After exhaustive studies on these, it has been determined that changes occur in the exterior of the planet, since, as occurs on Earth, there are periods closer to the great star than others.

Thus we can find storms caused by methane gas that, after condensation, precipitates on some of these planets.
