What is the relationship between crater size and meteor size?
The depth and diameter of the crater depends on the mass and velocity of the meteorite. A faster traveling or more massive meteorite will have more kinetic energy, so it will leave a larger crater [3-8].
What is the diameter of impact crater?
Meteor Crater
| Meteor Crater, also known as Barringer Crater | |
| Impact crater/structure | |
|---|---|
| Confidence | Confirmed |
| Diameter | 0.737 miles (1.186 km) |
| Depth | 560 feet (170 m) |
How big can a crater be?
Simple and complex craters can range in diameter. Some are a few dozen metres. Some are about 300 km! Impact basins are craters that are bigger than 300 km in diameter.
What is the largest impact crater on Earth?
The Yilan Crater is the largest meteorite impact crater on Earth in 100,000 years, reported Xinhua News Agency. The article noted that the crater was exposed in the Early Jurassic granite of the regional Paleozoic-Mesozoic granite complexes. China so far has two confirmed impact structures.
How did the density of the impact object affect the size of the crater?
This project demonstrated that objects with greater mass, higher velocity, and greater density will create wider and deeper impact craters than smaller and slower moving objects.
Do small meteorites create impact craters?
Small meteorites, which are more common than larger ones, generally cause little damage and do not produce significant craters. Such low-mass meteorites are slowed in the Earth’s atmosphere and thus their impact velocity is limited to that produced by gravitational forces. …
How does the diameter of a crater compare to the diameter of the impactor that makes it?
Typically, materials from space hit Earth at about 20 kilometers (slightly more than 12 miles) per second. Such a high-speed impact produces a crater that is approximately 20 times larger in diameter than the impacting object. The greater the mass of the impactor, the greater the size of crater.
What is the big crater in Arizona?
Barringer Meteor Crater
Barringer Meteor Crater and Its Environmental Effects. 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.
What is the largest size of crater called?
Specs: Also known as the Vredefort Dome, the Vredefort crater has an estimated radius of 118 miles (190 kilometers), making it the world’s largest known impact structure.
What factors affect the size of an impact 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 does the angle of impact affect the crater size and or shape?
In case of large impact craters, collapse of the central peak is more pronounced in the downrange direction. Effect of the impact angle on crater size: Crater size decreases proportional to the sinus of the impact angle α . This decrease is more pronounced for stronger materials.
Which is larger a planet or an impact crater?
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. The greater the mass of the impactor, the greater the size of crater.
What happens to the rock in an impact crater?
Sometimes the force of the impact is great enough to melt some of the local rock. If an impactor is large enough, some of the material pushed toward the edges of the crater will slump back toward the center and the rock beneath the crater will rebound, or push back up, creating a central peak in the crater.
Crater size is proportional to the mass of the impactor, and the velocity of impact. Given that the kinetic energy of the impact is related to mass and velocity, we can see that the experimental results support the theory that crater diameter is related to the kinetic energy of the impact.
Why are larger craters caused by larger bolides?
Larger craters result from larger bolide masses, assuming a constant impact velocity. Concepts (Level Two): Algebra Manipulation of multi-variable equations
