If you carefully consider all the objects of the solar system, then no doubt we can say that the Earth was lucky. When forming the planets, it was she who was destined to be in the right place, where all the factors for the development of life are most harmoniously combined. It is a paradox, but even with the development of progress in the field of space exploration and information accessibility, not all people have an idea about the cosmic parameters of the Earth, and it is precisely them who should be thanked not only to man, but to all nature for the opportunities that it provides for the development of the life cycle. It’s time to fill this gap.
Special thanks to orbit, atmosphere and axial tilt
Earth is the third planet remotest from the main star. The average distance to the Sun is about 149.5 million km, it has become optimal for her in terms of temperature ratio - not too hot in the daytime and summer, and moderately cold at night and winter.
The Earth’s orbit deserves respect for its location, not only because of the climate, but also because being in this part of the solar system has created opportunities for the formation of an atmosphere conducive to the origin of life, which is based on nitrogen and oxygen.
Pay attention to the angle of inclination of the earth's axis to the plane of the orbit. It is 23 degrees, thanks to it there are no completely shaded areas on the planet, each of them alternately receives the necessary amount of light and heat when changing seasons.
Air on Earth is not only oxygen ...
From childhood, people know about the importance of oxygen. However, rarely remember other components.
First of all, nitrogen belongs to them - this gas is even larger than the first in the atmosphere by volume and its main task is to neutralize the negative properties of oxygen. Sounds weird? In fact, there is nothing surprising, because if you recall the chemistry, it is known that the O 2 gas has the ability to create oxidative reactions, in its pure form it can even burn the airways! Therefore, nitrogen is a safety cushion for our mucous membranes of the nose and lungs.
And of course, a little carbon dioxide is present, only a few hundredths of a percent. Why so few if so many people on the planet exhale it every second? Everything is very simple: carbon dioxide is transferred from a person to plants, which, when exhaled, return oxygen to the atmosphere. Here is such a cycle!
The angle of inclination of the earth's axis and its gifts
As noted above, it allows any point on the planet to be charged with solar energy. But not only in this is his merit. The tilted axis allows you to observe phenomena such as seasons, which are a consequence of the fact that at each latitude the sun's rays are directed at different angles, changing them throughout all 365 days, as a result of which it becomes warmer or colder. And at the poles you can witness that for more than 180 days the sun does not set from the sky, and the other 180 days does not rise, because it illuminates the opposite pole. Thus, for the entire orbital cycle, two hemispheres are heated and cooled in turn. When it’s summer on one of them, and on the other at the same time, winter cold; with autumn and spring everything is the same. At each time of the year, the length of the day and night changes.
If the angle of inclination of the earth's axis were zero, then the picture would be more faded: day and night would consistently last 12 hours, and the time of year and temperature would be the same, depending on latitude. The equator would be an oasis of summer, autumn would not leave the middle latitudes, and at the poles there would be neither day nor night, but only eternal morning.
Special differences from neighboring planets of the Earth group
1. Our planet is the largest in size among them. Venus, and especially Mars and Mercury, are significantly inferior in size to it.
2. Only on Earth is there oxygen in sufficient quantity and in the right ratio, which is important for the presence of life.
3. Has the strongest magnetic field that protects against radiation and the largest natural satellite - the moon.
4. The only planet of the Earth group has a huge supply of water.
5. The distance to the Sun - about one and a half hundred million kilometers - turned out to be happy for her.
Conclusion
Earth can rightfully be called Paradise! Nowhere in the nearest space district are there such favorable conditions. And you need to thank for this space, which created a comfortable angle of inclination of the earth's axis and favorable orbital parameters. No neighboring planet has a satellite like the Moon, water, oxygen and life, which is beautiful in any case. And people only need to love and cherish her. Our planet deserves it.
