In the entire history of mankind's existence, we have not been able to fully study our own planet. But the facts that become known never cease to surprise us and motivate us more to know the world in which we live.
Do you know how fast spring moves across the Earth? And what state is the ozone layer in today? And the inhabitants of which island do not have to buy soap in the store, but only dig it in the yard?
Bright Side has collected another batch of amazing things you may not have known about our planet.
1. The hole in the ozone layer shrinks
The scientists' investigations showed that, compared to the year 2000 with 2015, the ozone hole (abnormal depletion of the ozone layer) above Antarctica has shrunk by 4 million square kilometers and continues to shrink.
Supposedly, such a "cure" could have been possible thanks to the Montreal Protocol approved in 1987, which prohibited the use of chemical substances that destroy the ozone layer. Scientists had previously pointed out that the ozone layer was recovering, but now they have received undeniable evidence of this.

2. −89.2 °С is the lowest temperature recorded on Earth
-89.2 °C has been the lowest temperature recorded on the Earth's surface. Such a cold "summer" day was July 21, 1983 in Antarctica, at the Vostok station.
3. Spring moves at a speed of 50 kilometers a day
The speed with which spring moves across the planet is about 50 kilometers a day. Scientists determined this by looking at the inflorescence of individual plants and paying attention to the flowering time of a species in different territories.
It was noted that, after the end of the cold season, the inflorescence of the same plant blooms within 24 hours in the territory that is 50 kilometers from the plant that has already flowered.
4. Tian Shan is the only mountainous place where human beings can not worry about their blood pressure rising
Increased blood pressure is a common issue when climbing high mountains. But on Earth there is a mountainous place where this does not happen with people. Tian Shan is a paradise for people suffering from hypertension. The local inhabitants usually have a little lower pressure in a normal state than the inhabitants of the plains.

6. Plate tectonics save the Earth from overheating
Earth is the only known planet to date with plate tectonics . Seven huge plates of the earth's crust that move in different directions at a speed of up to 10 centimeters a year.
Thanks to this tectonic system on Earth, the carbon cycle that prevents overheating of our planet is constantly carried out. Carbon is an important component that guarantees the possibility of the further existence of life on Earth.
7. The Amazon has a double underground river
Hamza is a theoretical river that until today has not been officially recognized. It runs parallel to the Amazon River at a depth of approximately 4,000 meters below ground. Its length is about 6000
kilometers, and its width is 400 kilometers. Hamza moves at a small speed, only several meters a year and this is slower than the movement of glaciers. At such a great depth, the waters of Hamza flow into the Atlantic Ocean.
8. The Pangea supercontinent is making a comeback
About 300 million years ago, all of Earth's continents were virtually united into one supercontinent: Pangea .
In the Jurassic era, Pangea was divided into two continents, each of them also, with the passage of time, separated. Thus, from the northern continent,
Laurasia, North America and Eurasia were formed, and from the southern continent, Gondwana, India, Australia, South America, Africa, and Antarctica were formed. According to scientists , within 250 million years, all the continents will be united again into a supercontinent - New Pangea.
9. In Antarctica, 3 trillion tons of ice have disappeared in the last 25 years
Research over the last 25 years has shown that 3 trillion tons of ice have disappeared from Antarctica. In 2017 alone, one of the largest icebergs in history broke away from the Larsen Ice Shelf. Its weight was more than 1 trillion tons, and its surface is half the size of the island of Jamaica.
10. The huge shadow that covers the Earth can be seen again in 2034
The unique phenomenon was captured by the space device in 2016 Himawari-8 belonging to a Japanese agency that collaborates with NASA :
initially, the planet reached the day, and then the entire territory of the Earth, diagonally from the left side to the right A huge shadow covered him.
The video was recorded on March 9 during a solar eclipse at a distance of 35 thousand kilometers from Earth. Such a phenomenon can now be seen in the spring of 2034.
Bright Side really liked the fact of the recovery of the ozone layer. And you, what information about our planet surprised you the most?
