Everything changes over time, and so does the Earth. The knowledge we thought was true before, a lot of it has “expired”.
For thousands of years, we still have not been able to fully understand the Blue planet. The simple reason is that over time, everything changes. What we thought was true in the past is no longer true today.
About 20 years ago, humanity was really worried about the huge holes in the ozone layer – especially in the Antarctic region.
But it seems that concern is now superfluous. A 2015 study showed that compared to 2000, the ozone hole has shrunk by more than 4 million square kilometers, and that number continues to grow.
The reason is also thanks to the cooperation of environmentalists who have helped governments around the world become aware of the harmful effects of chemicals that cause ozone depletion – such as CFCs (the substance found in chillers of the 20th century). Thanks to limiting products containing CFCs, the ozone layer is gradually recovering.
The temperature was recorded on July 23, 1983, at the Vostok meteorological station of Antarctica.
It is the Greek island of Kimolos , 53km 2 wide. A special feature of this island is that every time it rains, the ground will be covered with… soap bubbles.
The reason is because the soil of Kimolos contains soap clay – a form of natural soap used by indigenous people instead of ordinary soap.
Those are the tectonic plates – a total of 7 plates. Between these plates there is a process of carbon cycling, and that is why the Earth does not melt even though the core is full of extremely hot lava.
That river is called Hamza . The reason you have not heard of this name, is because it is an underground river, located up to 4,000m above the ground.
The river is nearly 6000km long, 400km wide, but flows at a very slow speed.
Research in 2017 found that Antarctica had lost 3 trillion tons of ice over the last 25 years. In 2017 alone, an iceberg in Antarctica broke off, and it alone weighed 1 trillion tons.
Just 2 words: Disaster! Plants could not grow, everything perished, and humans had no place to live.
