How big was the meteorite that hit Sudbury?
A meteorite believed to be 10 to 16 kilometres in diameter hurtles from space striking the area now known as Sudbury, Ontario (700 kilometres away)! An impact crater 250 kilometres wide is created, which forms the second biggest known crater on our planet (Figure 2).
How big was asteroid that killed the dinosaurs?
It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep.
Did any dinosaurs survive the meteor?
Birds. Most paleontologists regard birds as the only surviving dinosaurs (see Origin of birds). … Only a small fraction of ground and water-dwelling Cretaceous bird species survived the impact, giving rise to today’s birds.

How deep are the mines in Sudbury?
Located in the western portion of the City of Greater Sudbury, at 2,400 meters (7,800 feet), the site is one of the deepest mines in Canada — a distinction that brings with it certain challenges: High rock stresses determine the mining methods, which have been designed to minimize the impact of sub-surface seismic …
Why is Sudbury so rich in minerals?
Despite occupying one of the most mineral-rich areas of the world, large swaths of the Sudbury basin have remained unexplored. … The prevailing theory, said Farrow, is that the magma was rich in minerals, such as nickel and copper. When it hardened, it formed the mineral deposits that have defined the basin.
