However, the various facts presented in the article are aimed primarily at the development of the young man. However, if it also benefits the older generation, the author will only be happy.

Did you know that throughout the history of human existence, about 107 billion people have lived on Earth? To understand, let us remember that one billion is a thousand million!

At this point in time (2017), about 7 billion people live on Earth. This is despite the fact that about 200 years ago the population of our planet was within just one billion.

By the way, in a separate article we have already described in more detail the most interesting facts about the Earth - you can read it.

In 3rd grade, children wonder: where is the deepest place in the world's oceans? This is the Mariana Trench. Its depth is about 11 km. Just think about how deep this “hole” is!

Well, you probably might be curious what the highest point on earth is. This is Mount Chomolungma or, as it is also called, Everest. Its height is 8848 meters. This is the highest mountain and is located in the Himalayas (the mountain system of the Earth), located in China.

There are 252 countries in the world, but there are more than 7 thousand different languages.

The distance from the Earth to the Sun is 150 million km, and to the Moon is only 384 thousand km.

The Sun is a star that is the main one in our cosmic system. But there are a huge number of such systems. If you like interesting 3rd grade facts, then remember: space is infinite.

The largest country in the world in terms of territory is Russia. And the largest number of people live in China (more than 1 billion).

The first person to fly into space was Yuri Gagarin. He is known all over the world.

Some interesting facts from the animal world

Did you know that some species of scorpions can live for a whole year without eating?

Cats are not ordinary pets. Scientists have proven that they can heal their owners. Of course, they do this not consciously, but the benefits are obvious.

Dogs wag their tails for a reason. When they are happy, they move in one way, when they are worried, they move in another way. So you can tell your friends in 3rd grade about this.

Beavers are amazing animals that build their homes right in the middle of a pond. Their dams reach one meter in height, imagine!

A cow has four stomachs. They are needed in order to eat according to a certain pattern. Seeing a lot of grass, they fill their bellies with it without chewing. And then, when there is time, they regurgitate this grass and begin to chew thoroughly. Such animals are called ruminants, that is, those that chew the cud.

Children who enjoy 3rd grade fun facts already know that moles live underground. It should be noted here that their burrows can have up to six floors with many “closets” where they hide food for a “rainy day.”

The fastest creature on the planet is the peregrine falcon. She belongs to the falcon family.

But the smartest bird, no matter how surprising this fact may seem to you, is the crow. Its intelligence is so great that scientists have long been conducting research on this mysterious bird.

An ostrich has bigger eyes than a brain. Therefore, they are often compared to a very stupid creature.

A snail can sleep for up to 3 years. Can you imagine what a sleepyhead!

Also in the 3rd grade they actively explore the world around them. Below we provide information on this topic.

In Russia there is a unique Lake Baikal. It is the world's deepest and largest natural reservoir of fresh water. As you know, all water is divided into salty and fresh. You can’t drink salty water, so fresh water is of great value to all living people.

The largest desert on the planet is the Sahara. It is located in Africa. By the way, read interesting facts about Africa in a separate post.

Mice can jump to a height of almost half a meter and also swim excellently. Their teeth grow at a high rate and if they are not regularly filed, they will reach 12 centimeters in just one year. However, they simply would not be able to live with such long teeth. It is for this reason that mice constantly chew on something. By the way, they are capable of chewing through concrete and even lead.

It is human nature to think about our existence. Who are we? What are we? What are we here for? It is impossible to answer all questions. But we do know something for sure.

And it's so deep

But the Earth is simply nothing compared to what is beyond it. Here are all the satellites that orbit our planet every day.

But to get to the Moon, you need to travel thousands of kilometers. All the planets of the Solar System can be placed between the Earth and the Moon.

One of the peaks on Mars is Mount Olympus. Everest is like a small child compared to her.

And this is what Jupiter would look like to us if it were at the same distance as the Moon.

This is the amount of water on Jupiter's moon Europa compared to the amount of water on Earth.

This is how Jupiter protects the Earth every day from space debris and asteroids, “taking them aside.”

It is very easy to forget that we are in constant motion - every day, every second...

But our solar system is also moving all the time. We are now in the same position as 225 million years ago, when dinosaurs inhabited the Earth.

In fact, everything we can see is in this yellow circle.

And all the radio signals that humanity sends into space are here. No wonder we still haven't encountered intelligent life

But this is how many new planets we have discovered in recent years.

However, our galaxy is short compared to some others. Here's the Milky Way compared to IC 1011.

And they consist of such molecules. This is what we are.

But that's nothing.
Just imagine, in your body there are approximately 7,000,000,000,000,000,000,000,000,000 atoms, each of which is billions of years old.
This is truly what we all are and all we know yet.
