How do you determine crater size?

How do you determine crater size?

What influences the size and shape of a crater? The size and shape of the crater and the amount of material excavated depends on factors such as the velocity and mass of the impacting body and the geology of the surface. The faster the incoming impactor, the larger the crater.

How big can a meteor crater be?

Meteor Crater lies at an elevation of 5,640 ft (1,719 m) above sea level….Meteor Crater.

How big is a simple crater?

Impact craters are divided into two groups based on morphology: simple craters and complex craters. Simple craters are relatively small with depth-to-diameter ratios of about 1:5 to 1:7 and a smooth bowl shape.

Where is the largest meteor crater?

In South Africa, the Vredefort Crater, also known as the Vredefort Dome is the world’s largest known impact crater, according to NASA Earth Observatory.

How wide is the Barringer Crater?

1,300-meter
Barringer Crater, also known as “Meteor Crater,” is a 1,300-meter (0.8 mile) diameter, 174-meter (570-feet) deep hole in the flat-lying desert sandstones 30 kilometers (18.6 miles) west of Winslow, Arizona.

How large is an impact crater compared to the impactor?

Such a high-speed impact produces a crater that is approximately 20 times larger in diameter than the impacting object. Smaller planets have less gravitational “pull” than large planets; impactors will strike at lower speeds.

How big was the meteor that hit Arizona?

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.

Do all meteorites make craters?

Small meteorites, which are more common than larger ones, generally cause little damage and do not produce significant craters.

What’s the difference between a simple and a complex crater?

Simple craters, as their name suggest, are the most basic, and smallest, craters. Complex craters have a smaller depth-to-diameter ratio compared Page 2 334 to simple craters, a consequence of central peak and peak ring formation.

How big was the meteorite that hit Sudbury?

10 to 16 kilometres
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 wide is Meteor Crater in Arizona?

Barringer Crater, also known as “Meteor Crater,” is a 1,300-meter (0.8 mile) diameter, 174-meter (570-feet) deep hole in the flat-lying desert sandstones 30 kilometers (18.6 miles) west of Winslow, Arizona.

What is the diameter of the Chicxulub crater?

The crater appears to have a diameter of ~180 kilometers, which makes it one of the largest confirmed impact structures on Earth.
