What is Barringer Crater?

Barringer Crater, otherwise known as Meteor Crater, is one of the most important and greatest impact craters on the planet. Barringer Crater is located 43 miles east of Flagstaff in Arizona and has a diameter of about 1,200 m (4,000 ft), 170 m deep (540 ft) and has a edge that rises 45 m (150 ft) from the surrounding desert terrain. In the crater is about 240 m (800 ft) rubble that covers the crater floor. At that time, the terrain was much more humid and cooler than today, and grasslands occupied by camels, woolen mammoths and giant ground sloths would be. Nickel-Zeleza meteorite about 50 meters (164 ft) across countries on the ground to 12.8 kilometers per second (28,600 mph). When he entered the atmosphere, it is estimated that the bolide had a weight of 300,000 tonnes, half of which was lost due to friction at a time when a reball surface. Meteorite hit the ground at an angle of 80 degrees, ejected 175 million tonnes of rock and produced an explosion equivalent to about 2.5 TNT megatons, or 150 times as intense as atomic bombs that destroyed Hiroshiand Nagasaki. Thousands of plants and animals around them would be immediately evaporated.

initially thought it was the result of a volcanic steam explosion, Barringer the crater is the first crater to be recognized as a meteorite impact. In 1903, Daniel Morreau Barringer, a mining engineer and entrepreneur, was the first to propose the theory of impacts that was considered scientifically doubtful at that time. It was assumed that the impacts of the meteorite were very rare. Barringer tried to dig a meteorite from a nickel that created a crater but failed. The consensus that Barringer Crater was created by the meteorite of the Daybud to fully appear until the 1950s, as planetary science has become more mature. Only in 1960 was Eugene Shoemaker, a great planetary scientist, in the crater of minerals that finally showed that this was due to the impact of meteorite. Since then, many other craters have been discovered around the world.
