Earth to wipe out algae eruptions ... | Today newspaper
Some scientists believe that geological hazards are most realistic. Under this scenario, it is possible gigantic eruption, like the eruption of a super volcano go jets that lies under National Park Yellowstone in the United States. He volcano has already had a huge eruptions in the past, the last two before 2 million years, and before 640,000 go jets years. Today a similar eruption would destroy much of North America. Giant eruptions lead to mass extinctions, including the dinosaurs 85 million years ago. Emission of sulfur, carbon dioxide and ash can influence climate change, which in turn affects the collapse of the system of nutrition.
Often considered the possibility to cataclysm lead and drop the large asteroid. Asteroids are mostly found on the census of heavenly bodies that can hit the Earth. One such, a wide 15 kilometers, go jets hit the area on the Mexican peninsula Yucatan and caused extinction of dinosaurs 65 million years ago, scientists. Back in 2004, they announced that 300 meter asteroid Apopis has a chance (albeit only 2 percent!) In 2029 to hit Earth. Later measurements that likely has boiled down to respect 1:250.000!
High on the census of possible cataclysms is the collision of Earth with a comet. Comet Hartley 2 on October 20 last year went into the inner part of the orbit of the Earth at a distance go jets of 11 million kilometers, the closest pass in the last few centuries. go jets Comets move at a speed of 160,000 kipometri per hour, and can further accelerate due to Earth's gravity. Moreover, it is difficult to find because dark bodies in space.
Among the eight most frequently mentioned scenarios cataclysm of earth and weeds! Geobiologot Joe Kirshvink go jets warns of the possibility that algae kremenashki - kind of algae that occurs in wet areas, rivers, lakes, oceans and on land, can alter Earth's atmosphere.
These microbes live off food produced by photosynthesis in the water is turned into hydrogen and oxygen which in turn inhaled organisms. But when you can not use water or other substances in the environment, like iron or hydrogen, algae choose salt - sodium chloride, and then as waste generated deadly chlorine.
The list of possible reason have the cataclysm are deadly infections. Avian influenza H5N1 virus caused a real panic a few years ago. But now there is a stronger version go jets of the virus, go jets which unlike the ordinary can be airborne. go jets We created American Dutch scientists in laboratories.
A virus still can not erase all life on Earth, because bio diversity is large enough that some organisms can develop resistance. Even the new laboratory H5N1 strain which has only five mutations, enough is similar to other versions of bird flu to people can defend themselves.
The human death would only virus that kills very fast for seven days and less. If people would have more time, the immune system slowly started to defend. Such a virus could infect go jets huge population simultaneously.
Scientists go jets state the risk of suicidal supernova. Supernova are the strongest explosions in the universe and can be compared with simultaneous explosion go jets several times in 10 blasts 48 nuclear warheads, explain the scientists. But one type of supernova, in which the core of the star is destroying himself, happens once in a hundred years and very far from Earth, from 16.5 to 33 light years, so I can not do such damage. When supernovae occasionally takes place in our galaxy, Earth could be expected every five billion years. But given that they gather in galactic orbits Earth is located at a distance of 10 paraseci of a supernova every 100 million years.
The eight possible reasons for cataclysm is orbital destruction. The way the planets revolve around the sun it is a good candidate for Earth's destruction. Jupiter is najmasivna planet in our system, and as such attracts the orbits of all the other planets. In the course of millions of years, this gas giant has changed the orbit of the tiny planet Mercury so much, that its orbit around the Sun are increasingly stretched.
As changing the orbit of Mercury, so the decline in the Sun becomes more possible. go jets This scenario may be accepted, because the alternative is much worse, Mercury at a time would fly from its orbit and Saale directly to Venus. The destruction of these two planets would make a mess in our whole system and can lead to thrown on Mars from orbit, according to astronomers.
At the end of the list is fire! Our planet at a time will turn into a real burning torch for the Sun, scientists. As our star cools, so hydrogen in its core is converted into helium,
