Astéroïde chicxulub

The impact of the Chicxulub asteroid produced a shock wave and a blast of air that expanded across the seas, on the coasts and in the continental interior. Generating winds well in excess of 1000 kilometers per hour near the impact site. The pressure and winds generated killed the vegetation and any animals that live in nearby ecosystems. The radius of the area damaged by the explosion is …

Chicxulub crater formed by asteroid that killed the dinosaurs reveals broken rocks can ‘flow like liquid’ after a massive impact. Researchers studied 115-mile wide crater created by dinosaur …

The Chicxulub impactor (/ ˈ tʃ iː k ʃ ə l uː b / CHEEK-shə-loob), also known as the K/Pg impactor and (more speculatively) as the Chicxulub asteroid, was an asteroid or other celestial body some 11 to 81 kilometres (7 to 50 mi) in diameter and having a mass between 1.0 × 10 15 and 4.6 × 10 17 kg, which struck the Earth at a velocity of roughly 20 kilometers per second at an angle of …

In fact, they calculated that an asteroid strike of Chicxulub’s size had only a 13 percent chance of leading to a mass extinction. The fatal factor at the impact site, now below the ocean off the coast of Yucatan, Mexico, was the large amount of hydrocarbons lurking in the rocks that were vaporized into soot when the asteroid hit.

A newly published study of rock samples extracted from the Chicxulub Crater’s inner rim reveals a detailed look at what happened in the wake of this catastrophe. Though layers of rock accumulated over thousands of years are usually indicative of mere ticks on the geological clock, the Chicxulub Crater is different–hundreds of feet of sediment built-up rapidly in mere days. Here’s what we’ve …

Astronomers announced more proof today (Feb. 7) that the Chicxulub asteroid impact 65 million years ago led to mass extinction of dinosaurs. The idea was not always universally accepted.

Chicxulub inner crater at the same scale as the Washington D.C. – Baltimore area. Alternative theories. Although, the theory that the impact at Chicxulub was the one that triggered the extinction of the dinosaurs is widely accepted, some scientists challenged it. A paper published at the US Proceedings of the National Academy of Sciences argues that the impact predates the K-T boundary by …

Asteroid Chicxulub je hypotetické těleso o velikosti asi 11 až 80 kilometrů, které dopadlo před 66 miliony let do oblasti současného Mexického zálivu (výběžek poloostrova Yucatán) a zřejmě bylo jednou z hlavních příčin hromadného vymírání druhů na konci křídy. Při něm vyhynulo na konci křídové periody druhohorní éry asi 75 % druhů tehdejších organismů …

The generation of what has become known as the Chicxulub Crater was an astonishing event. The initial hole punched in the Earth would have been about 30km deep and 80-100km across.
