How big was the meteor that hit Arizona?

Barringer Meteor Crater and Its Environmental Effects. Forty-nine thousand years ago, a large 30 to 50 meter diameter iron asteroid impacted the Colorado Plateau in northern Arizona. The resulting massive explosion excavated 175 million tons of rock, forming a crater nearly a mile wide and 570 feet deep.

How long did dinosaurs survive after asteroid?

‘It was only around 15 million years after the non-bird dinosaurs disappear, during what’s termed the Oligocene Epoch, that we started to get really big mammals. This is when rhino-sized animals start to reappear.

Yucatán Peninsula
The crater left by the asteroid that wiped out the dinosaurs is located in the Yucatán Peninsula. It is called Chicxulub after a nearby town. Part of the crater is offshore and part of it is on land. The crater is buried beneath many layers of rock and sediment.

What would happen if the Earth was hit by a large asteroid?

The energy of the impact will vaporize the asteroid and a large amount of the Earth’s crust, creating a crater more than one hundred kilometers across, throwing all that rock into the air. Some of this debris will be going so fast that it will fly right out of the Earth’s atmosphere and go into orbit around the Earth.

How big was the asteroid in deep impact?

On July 1 of that year, Deep Impact rendezvoused with Comet 9P/Tempel 1 (the official name is usually shortened to Comet Tempel 1). Deep Impact was about 10.8 feet (3.3 meters) long, 5.6 feet (1.7 m) wide and 7.5 feet (2.3 m) high.

What would happen if the Earth stopped spinning?

At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

What would happen if the sun exploded?

The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. … During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
