What happens if a meteorite hits the ocean?
To date, scientists have discovered more than 800 large-diameter asteroids whose orbits can intersect with the Earth. We can say that these 800 asteroids threaten us and there is a good chance that one of these blocks may encounter our planet. And every year there are very disappointing changes, because the number of dangerous cosmic bodies for us is increasing. By the way, it's not that the number of meteorites in space is growing, just new technologies detect previously undetected objects. Unfortunately, modern science does not eliminate the meteorite, which can directly crash into the Earth. However, the simulation of the situation that will occur when a kilometer meteorite collides with the surface of the ocean, managed to do. This was done by scientists from Arizona, who are engaged in their research at the Institute of planetary Sciences.
They imagined that an asteroid 1 km in diameter entered the atmosphere of the planet at a speed of 20 kilometers per hour. Modeling of this situation showed that after the collision of such an asteroid with the ocean, a monstrous fountain with a diameter of one thousand kilometers will rise, the spray of the fountain will carry into the atmosphere and near-earth space about 20 billion tons of water. Naturally, there will be a huge tsunami, which according to researchers will not cause much harm. Chlorine and bromine, which are in large quantities in seawater, will destroy the ozone layer of the Earth. Although the "ozone hole" above the site of the fall will be small, it will gradually increase and thus disappear about 80% of the ozone layer. After that, all living organisms will be subjected to harsh sunlight, because the ozone layer - the main defender - will no longer.
Of course, people will be able to find some protection, but plants, animals and marine phytoplankton will be on the verge of extinction. Most likely, such a disaster and destroyed the dinosaurs millions of years ago, when such an asteroid collided with the Earth.
What will happen if the planet will crash asteroid diameter is not 1, and 10 kilometers, scientists did not represent enough mentally multiply all of the above consequences 10 times. Although in principle, there is no simulation is clear - few will be able to survive. And the old Earth will change beyond recognition. Fortunately, such disasters happen very rarely. But asteroids with a diameter of up to 200 meters can fall often. This is exactly what the Norwegian scientists have been doing : what consequences can the tsunami formed after the collision of the asteroid and the Earth cause?
Scientists have confirmed that the force of such a tsunami will be 200-300 times greater than that of the Asian tsunami of 2004. But immediately comforted : tsunamis from earthquakes is much longer, and so our giant tsunami may disintegrate even before you get to the mainland.
Much more dangerous will be hurricane winds and splashes that appear after the collision. Again, the simulation showed that water masses not only will wsmouse up, but will rush in the transverse direction with terrifying speed, sweeping away everything in its path. There is also an assumption that the water that enters the atmosphere will return in the form of heavy rain, but scientists do not focus on this fact a lot of attention. But why? Suddenly water will pour and pour? Whether it is necessary for mankind to be saved, like Noah in the ark?
