The ozone layer in the North Pole has lost one million square kilometers.

 The ozone layer 

 Reports indicate that by the end of March, a large hole in the ozone layer above the North Pole had closed. The huge cracks in the ozone, which is about one million square kilometers, has disappeared. This comforting discovery was made by the European satellite system Copernicus.

 The first ozone hole was discovered at the North Pole in January 2011. But it was small. The ozone layer protects the earth from the sun's ultraviolet radiation, which causes skin cancer. The big gap has closed in recent days.

 But the hole has nothing to do with the lockdown that has been part of the fight against Kovid or the lack of air pollution. Instead, the ozone rupture and its changes are caused by the polar vortex phenomenon, which brings cold air to the polar region.

 Most ozone depletion takes place where the air temperature drops below minus 42 degrees. This is why the ozone rupture first appears above the South Pole. The temperature at the South Pole is minus 62 degrees. However, the polar vortex phenomenon in the North Pole has led to a decrease in temperature and an ozone depletion.

 Temperatures in the poles are typically about 20 degrees higher than when the polar vortex is experienced. This year, the Polar Vortex was so strong that it was getting colder. This led to strong ozone depletion. Ozone depletion is strongest when temperatures drop below minus 42 degrees. But over the past few days, the polar vortex has weakened and ozone depletion has been reduced.

Mysteries of the Kola Bor crater

Is hell underground ...?  Mysteries of the Kola Bor crater ... kola superdeep borehole  The Kola bore-hole project celebrated its 25th anniversary in 2006 at the Sapolini station near Le Marmamance, Arctic. What is the Kola bore-hole project .....? The project began on May 24, 1970, on the Kola Peninsula in the old Soviet Union's Pichinsky district, with the goal of digging as deep as possible into the earth's crust as far as possible for the modern world. The project, which is still the deepest artificial point on earth, reached a depth of 12 km in 1983 and was only 262 meters over the next ten years. In 1995, when the total depth reached 12,262 m (40,230 ft), the project was unexpectedly discontinued. Scientists were initially surprised to find fossils of micro-organisms in the oceans four kilometers deep, and later, they found out that all textbook predictions were false. The granite was much hotter than predicted when the pit was gone. At ...

The Sagrada Familia church of Spain

The Sagrada Familia of Spain Jacob Maliecal, "The Sagrada Familia of Spain (Barcelona), which continues to be built after a hundred and thirty years  Work began in 1882, and today was the first time that the church was still under construction. It was made possible when he visited Barcelona as part of a Mediterranean cruise voyage with Kerry friends in Switzerland.  Designed by the then famous architect of Spain, Anthony Gaud ((1852-1926), the church was declared a Pope John Paul Basilica in 2010 and a UNESCO Heritage Site. Anthony Gowdy dedicated his life to building this shrine. Only a quarter of it was completed during his lifetime.  Ten of the 18-tower mosque's plan was completed.  The Goudy Plan was drawn up by the Crucifixion of Jesus to the Sagrada Familia Church. In the Gothic style, he plans to interiorize the temple into a forest, into a series of shingles and columns. Characteristics of this shrine: ...
