How many miles was the asteroid that killed the dinosaurs?

Folks in the asteroid camp think the impactor was about 6.2 miles (10 km) in diameter. Asteroid or comet fragment, the space rock was big enough to spur one of Earth’s six known mass extinctions.

How did a meteor wipe out the dinosaurs?

As originally proposed in 1980 by a team of scientists led by Luis Alvarez and his son Walter, it is now generally thought that the K–Pg extinction was caused by the impact of a massive comet or asteroid 10 to 15 km (6 to 9 mi) wide, 66 million years ago, which devastated the global environment, mainly through a …

Where did scientists find a crater from an asteroid about 6 miles in diameter that likely contributed to the extinction of dinosaurs?

The impact site, known as the Chicxulub crater, is centred on the Yucatán Peninsula in Mexico. The asteroid is thought to have been between 10 and 15 kilometres wide, but the velocity of its collision caused the creation of a much larger crater, 150 kilometres in diameter – the second-largest crater on the planet.

Did volcanoes wipe dinosaurs?

Researchers dig deep into the theory that carbon dioxide from volcanic eruptions in India helped kill off the dinosaurs. If you asked Joe Blow on the street how the dinosaurs went extinct, he’d mostly likely say an asteroid wiped them out, but the truth is a little more complex than that. …

Can you visit Chicxulub crater?

You can visit the Museum of Science of the Chicxulub Crater in Merida, Mexico, to learn more about this crater. Scientists believe that the comet that created this crater is also responsible for creating the beautiful blue water sinkholes that dot the area around Merida.

Did the Chicxulub crater killed the dinosaurs?

It coincides with the K–Pg boundary, the geological boundary between the Cretaceous and Paleogene. The impact associated with the crater is thus implicated in the Cretaceous–Paleogene extinction event, including the worldwide extinction of non-avian dinosaurs.
