Asteroids 'baked' Earth

A collision with an ancient asteroid may have triggered a global fire storm, burning each tree and grass on the surface of our planet.

According to the R&D magazine, a report of the University of Colorado Boulder, the asteroid, about 60 km ² in size, hit a region of Mexico in the dinosaur era, blowing fire storms and burning 80% of the same. species on earth.

The researchers say it has detected a number of soot in sediments dating back 66 million years. Based on the computer model, scientist Douglas Robertson and colleagues identified the collision at the time, which vaporized huge blocks of rock, and flew the material up to the upper atmosphere.

When returning to the ground, these forms of matter caused the atmosphere to heat up to temperatures of more than 1,480 degrees Celsius within a few hours, enough to kill all beings who had not yet been able to sneak into the ground or shelter caves.
