About 65 million years ago.
Giant meteors have hit the Earth many times. Probably the most destructive - so far - was Chicxulub which "may" have been the cause of the dinosaurs extinction.The most notable crater in the US is - not surprisingly - called meteor crater. Located in the Arizona desert, near Winslow.
There are plenty of famous meteors, to know which one specifically you are speaking about, I would need a name. The most famous is probably the one that many believe killed all the dinosaurs. This meteor is estimated to be about 6 miles wide, and created a crater about 110 miles across. Many believe that the Chicxulub Crater in Yucatan, Mexico is this meteor.
An uncommon belt of dust with radioactive elements is found just where many dinosaur remains cease to be found (chronologically speaking). The layer of dust corresponds to an impact of a giant asteroid in what is now the Gulf of Mexico called the Chicxulub crater, just north of the Yucatan peninsula.
Volcanoes take many years to form, but it also depends on the type of volcano. A stratovulcano for example exists of multiple layers. This takes many years. Because of an erruption a volcano often collapses or shrinks, so then it takes many years again. A new volcano can also be formed in the crater of an old volcano. Check the link under the related links section for detailed information about volcanoes.
Chixulub on the Yucatan Peninsula in Mexico is famous for being near the epicentre of a meteorite impact that caused the final extinction of many animals (most famously all non avian dinosaurs) at the end of the Cretaceous Period 65.5 million years ago.
The Chicxulub impact crater was formed approximately 66 million years ago at the end of the Cretaceous period. This impact event is strongly associated with the mass extinction of the dinosaurs and many other species.
I guess you mean the crater in Mexico where many think the meteorite that killed the dinosaurs fell. That is the Chicxulub crater, covering almost half of the Yucatan peninsula.

Which one? There have been many. Possibly you are referring to the Meteor Crater in Winslow, Arizona? Or the Chicxulub impact that probably killed off the dinosaurs (and 75% of all other life on Earth) 65 million years ago? That one struck off the Yucatan Peninsula in Mexico.
That depends on where the crater is, and how it formed. Meteor craters on the Moon or Mars? Nothing generally fills them up, and lunar craters are still visible after many hundreds of thousands of years. On Earth? A meteor crater will, eventually, fill with dust or dirt and water. A good number of meteor craters are visible as circular lakes. The Meteor Crater in Barringer, AZ is still empty after 50,000 years. Volcanic craters sometimes fill with lava, or with dirt and water. Crater Lake in Nevada is a .... lake, filled with .... water.
formed by a volcano many, many years ago.
Mt. Hood was formed 2,000 years ago.
How many recorded times has Crater Lake erupted

No. Pangaea was formed many, many millions of years before Christ
about 4.5 billions years ago.
