Recent research shows that the blue planet Earth we live in is about 4.54 billion years old. The oldest remains of modern humans are about 300,000 years old. I mean, we’re pretty young for Earth, but we’re still around for a long time. Since mankind has developed and made scientific studies to get to know the earth, our home, a little better And we’re starting to understand.

We have a lot of basic information about the world we live in. However, it is clear that there are still untouched places, unexplored places and inexplicable secrets. Some known information about the world It consists of quite complex technicalities and, let’s face it, it doesn’t appeal to everyone. Let’s put the intricate details aside and take a closer look at some interesting facts about the Earth in a way that even those with no knowledge of the subject can understand.

Interesting facts about the world:

If the Earth exists, it exists thanks to tectonic plates:

Earth is the only planet in the solar system known to have plate tectonics. outer shell of the planet, divided into areas called tectonic plates. These plates float on the magma in the interior. When tectonic plates collide, one sinks beneath the other, creating a fresh crust.

Movements of tectonic plates cause earthquakes, volcanic eruptions, the formation of mountains and hills, gullies under the oceans and causes tectonic resurfacing. These movements also fuel the carbon cycle by causing microscopic plants to sink to the ocean floor when they die.

The carbon cycle is extremely important for our Earth and for us humans and other living things that live on it. Thanks to the transformation of carbon residues in the earth The greenhouse effect observed on the planet Venus does not occur. In other words, if carbon transformation didn’t happen due to tectonic movements on Earth, the beautiful planet would be empty in space like a fiery sphere.

There are several basic elements that make up the Earth:

If we think of planet Earth as an apple that we can take in our hands, chop with a knife and examine, four basic elements appear before us. This one iron, oxygen, silicon and magnesium. There are, of course, many more compounds, but these elements are the most concentrated.

Our world consists of 32.1% iron, 30.1% oxygen, 15.1% silicon and 13.9% magnesium. to the center of the earth when we get to the core The iron content we encounter can be up to 88% and the oxygen content up to 47%.

The Earth’s atmosphere is about 10 thousand kilometers long:

Since the concept of the infinity of the universe can be a much more complex issue than the human mind can conceive, Some concepts of distance may come as a surprise to us. However, if we think about the entire universe, the fact that our planet’s atmosphere is 10 thousand kilometers long is a minor detail.

Although the Earth’s atmosphere has the thickest layer in the first 50 kilometers, its total length is about 10 thousand kilometers. Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere The air pressure and density in the Earth’s atmosphere, which is made up of five main layers, called the Earth’s surface, decreases with distance from the surface.

Of course, it is not possible to talk about the same density for 10 thousand kilometers. The layer where the atmosphere is most dense is 11 kilometers from the surface. This density gradually decreases and disappears by merging with the outer space in the last layer, the exosphere. The exosphere, unlike the atmosphere in general, does not behave like a gas. This layer consists of freely moving particles, which often escape into space.

Our world is like a big magnet:

At the innermost point of the Earth, there is an outer core that has melted. This outer core exhibits continuous convection motions. As a result of these movements A magnetic field called the magnetosphere is created. Due to the magnetic field, the effect of which reaches thousands of kilometers from the surface, it is possible to see our world as a huge magnet.

Of course, we can’t take our Earth with this magnetic field and stick it in a refrigerator. Well, if you say what works, We recommend that you look at the sun. The sun, which is the basis of life by providing heat and light, actually contains quite intense radiation. Thanks to the magnetosphere, this radiation, which tries to penetrate our earth with the sun’s rays, is pushed into space and sent to space by passing through the planet tangentially.

The rotation of the Earth on its axis does not last exactly 24 hours:

It takes 24 hours for the earth to rotate on its axis, and this period is referred to by us humans as a day. Really? In fact, the rotation of the Earth on its axis it lasts exactly 23 hours 56 minutes 4 seconds and this period is called Starry Day by astronomers.

But shouldn’t the whole day-night cycle in time be turned upside down because of this loss of 4 minutes per day? no because There is another cycle called the Day of the Sun. The earth also revolves around the sun and the sun also moves about 1 degree. Thanks to this small movement, the period of time, which seems to be a daily loss, is tolerated and the daily system continues to function smoothly.

A year is not 365 days:

The concept we call a year is the time that occurs due to the complete rotation of the earth around the sun. Contrary to what is known, this period is It’s not 365 days, it’s 365.2564 days. We close this apparently small decimal day difference with the leap year application. That’s why February is one day longer every four years. In other words, the Earth actually has more complex movements than we think, but we do our best to work these movements into certain patterns.

The Earth has two other satellites with which it shares a common orbit in addition to the Moon:

The moon is the satellite of our earth. This is one of the most famous basics. However, there are two other satellites that Earth has in common. Near objects on Earth 3753 Cruithne and 2002 AA29, part of a large group of asteroids called earthquakes, are locked in a common orbit with Earth.

The asteroid 3753 Cruithne is about 5 kilometers in diameter and has been called Earth’s second moon. It’s not actually in orbit. Nothing but It has a synchronized orbit with the Earth. In this regard, it seems to follow our planet, but it follows a different path that it creates around the sun. Still, it’s possible to say that it follows a synchronous orbit enough to claim the title of Earth’s second moon.

The blue planet we’ve been living on for hundreds of thousands of years From some little-known facts about the world We have explained these details in a way that everyone can understand. Of course, all this information has a lot of technical details. You can share your thoughts on the topic in the comments.
