What size meteor hit Arizona?
30 to 50 meter diameter
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 big of a crater does an asteroid make?
Typically, materials from space hit Earth at about 20 kilometers (slightly more than 12 miles) per second. Such a high-speed impact produces a crater that is approximately 20 times larger in diameter than the impacting object.
How big was the meteor which hit Arizona 50000 years ago?
The big hole in the ground — 570 feet deep and 4,100 feet (1.25 kilometers) across — was blown into existence 50,000 years ago by an asteroid roughly 130 feet (40 meters) wide.
How big is the biggest asteroid crater?
The Vredefort crater /ˈfrɪərdəfɔːrt/ is the largest verified impact crater on Earth. It was 160–300 km (100–200 mi) across when it was formed; and what remains of it is in the present-day Free State province of South Africa. It is named after the town of Vredefort, which is near its centre.
How big was the meteor that hit Grand Canyon?
150-foot-wide
Fifty thousand years ago, give or take a millennium, a 150-foot-wide iron-nickel meteorite slammed to Earth, killing every living thing within a few miles.
How big is the crater in Arizona?
Meteor Crater measures 0.75 miles (1.2 kilometers) across and about 600 feet (180 meters) deep.
Did a meteor create the Grand Canyon?
And unlike the Grand Canyon, which was carved over millions of years, Meteor Crater was excavated in a few seconds. The culprit responsible for the crater was over 4.5 billion years old.
Where is the largest Meteor Crater in the USA?
It is also referred to simply as “Meteor Crater”. The crater is located approximately 69 km east of Flagstaff, near Winslow in the northern Arizona desert of the United States. It is the largest impact crater yet discovered in the United States, and one of the best preserved on earth.
How big would a meteor have to be to destroy Earth?
Ultimately, scientists estimate that an asteroid would have to be about 96 km (60 miles) wide to completely and utterly wipe out life on our planet.
How big was the meteor that hit the dinosaurs?
between 10 and 15 kilometres wide
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.
Why are there no dinosaurs in the Grand Canyon?
There are no dinosaur bones in the Grand Canyon The rock that makes up the canyon walls is vastly more ancient than the dinosaurs – about a billion years more ancient, in some cases – but the canyon itself probably didn’t form until after the dinosaurs were long gone.
How big was the meteor that hit New Mexico?

Was Arizona once an ocean?
Arizona was still covered by a shallow sea during the ensuing Cambrian period of the Paleozoic era. Brachiopods, trilobites and other contemporary marine life of Arizona left behind remains in the western region of the state. The sea withdrew from the state during the Ordovician and Silurian.
