According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across.
How big was the meteor that killed all the dinosaurs?
The asteroid was about 7.5 miles (12 kilometers) in diameter and was traveling about 27,000 mph (43,000 km/h) when it created a 124-mile-wide (200 km) scar on the planet's surface, said Sean Gulick, a research professor at the University of Texas Institute for Geophysics, who led the study.
How big was the shockwave that killed the dinosaurs?
The impact did generate a massive tsunami and it was one of the largest waves Earth ever experienced. The asteroid that hit the Earth 66 million years ago was 8-10 km across and traveled from the northeast at a velocity of 20 kilometers per second which is 45,000 miles per hour (!)
What happened to the meteor that killed the dinosaurs?
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.
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 long did dinosaurs live 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.
How far inland would a 1 mile high tsunami travel?
When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. However, tsunamis can surge up to 10 miles inland.
How big of a tsunami would an asteroid make?
An asteroid 5-6 kilometers in diameter impacting between the Hawaiian Islands and the West Coast of North America, would produce a tsunami which would wash out the coastal cities on the West coasts of Canada, U.S. and Mexico and would cover most of the inhabited coastal areas of the Hawaiian islands.
How much damage would a 1000 foot asteroid do?
Scientists observed that the branch from the Taurid Stream could catapult a 1000-foot wide asteroid into the earth's oceans or land mass. A rock of this magnitude could wipe out entire regions if it hits earth. The aftermath scenario is a catastrophic picture of immense destruction and carnage.
What size meteor would destroy a city?
If an asteroid the size of an apartment hits Earth, this blow could possibly destroy a small city. If an asteroid the size of a 20-storey building hits Earth, this blow can completely flatten a small country.
