What causes the formation of a crater?

Answer 1

craters are formed by asteroid impacts, comets colliding with the Earth even Volcanic eruptions.

The biggest asteroid impact is in the Yucatan Peninsula this thing is over 100 million square miles it is also the key suspect in the extinction of the Dinosaurs.

We now know that comets can break up when they get close to a planet. In 1994 a comet that we called Shoemaker-Levy 9 collided with Jupiter but before it hit it broke up into smaller fragments so basically it rained down comets onto the planet. The same thing has been known to happen on Earth about 35 million years ago a meteor broke apart one piece of it landed in what is now the Chesapeake Bay the other piece landed in Siberia.

We know that volcanoes have a history of collapsing (think of Mt. St. Helens in 1980) the same thing can happen with Super Volcanoes.

There is a theory about how this monsters can be formed. Millions of years ago where the Caldera is today there would have been a massive volcano, when it erupted it exploded out would where it should have gone extinct but instead the Caldera just keeps filling up with magma instead which causes a massive problem for the human race.

Three examples are:

Yellowstone Caldera

Long Valley Caldera

And Lake Toba.

Answer 2

A crater is either formed by the impact excavation of a meteor collision, or from the explosion of magma and gas from underneath a volcanic plug or dome.

Answer 3

Basically two things: either something volcanic erupting or a meteorite impacting.

Answer 4

It forms by volcanic activity in the vent of a volcano.

Answer 5

a crater forms by the pressure of the magma

Answer 6

Craters form when an asteroid or meteor collides with the planet or moon.

or

When a volcano forms.

Answer 7

it forms by the pressure of the magma
