How often do objects big enough to create craters like the Meteor Crater impact Earth?

We can't be certain, but on the order of once in 50,000 years. It depends on where the object strikes; 15,000 years ago, a comet or large meteorite impacted northern Canada, causing an abrupt cooling period known as the Younger Dryas. About 5300 years ago, an object may have crashed into the Indian ocean, causing tsunami waves that would have swept the shores of eastern Africa, western Australia, most of India, and into Mesopotamia. This possible tsunami may have inspired the similar "world wide flood" legends such as the Gilgamesh epics in Sumeria, some Dreamtime stories from the Australian native cultures, and a guy named Noah.
And then there was the Tunguska, Siberia explosion in 1908....

What year was the meteor crater made in AZ?
The Barringer Meteor Crater in Arizona was formed about 50,000 years ago.
What effect will a 65ft diameter asteroid have on earth if it does hit the earth?
It will create a crater similar to the Barringer crater (Meteor crater).Where it actually hits will determine the overall destructive effect.Oceans: TsunamiCities: Total destruction.Barren land: Crater.
What are two variables that could cause meteorites to form different sized craters?
There are a number of factors that determine the size and shape of a crater. The two most significant are the mass of the impactor, and the speed. Other influential factors would include the composition of the object (solid rock or more aggregate, like pebbles? Ice?) the shape of the object, and the composition of the impact site. If it is on dry land, it will be more likely to leave a visible crater, while a water or marshy impact site would be quickly erased. If a water impact, the depth of the water and the topography of the surrounding seas would be vastly important. A strike in a deep ocean basin might be relatively mild, while a water strike in the South China Sea or Gulf of Mexico, with the constricted water flow, might result in catastrophic tsunamis inundating the surrounding areas.
What are depressions on the moon called?
The maria (singular mare) on the moon contain igneous rocks and are dark-colored, fairly flat regions. Craters, however are circular depressions on the moon formed by the impacts of meteoroids.
How is the size of a crater related to the size of a meteorite?
Typically the larger and deeper the dimensions of a crater, the more energy (KE) the meteorite had on impact. This generally means that a meteor was massive enough to breach Earth's atmosphere without loosing significant amounts of material. Thus we can infer that the larger the impact crater the more massive the meteor was. As for the actual dimensions, little inference can be made as mass and size do not always correlate directly.

When meteors or other objects stike the moon what do they create?
Impact craters. The size of the crater is related to the speed of the impact and the size of the object.
When meteorites or other objects strike the moon they create what?
craters
When meteorites or other objects strikes the moon they create?
craters
Why did the comet impacts of 1994 not create craters on Jupiter?
Jupiter does not have a solid surface on which a crater could form.
What is it called then objects hit the moon and create craters?
A Impact Basin
How might geologists distinguish an impact crater on earth such as Meteor Crater in Arizona from a volcanic feature?
A large meteoric impact such as Meteor Crater in Arizona, displaces the sedimentary rock that has existed before impact. On the rim of Meteor Crater are displaced boulders from lower depositional areas. Small fragments of the meteor are found around the entire area of the impact, and they may be detected with something as simple as a magnet. Features that indicate a volcanic event, like volcanic cinders or quantities of extrusive igneous rock , would also be missing from the impact site.

When meteorites or other objects strike the Moon what do they create?
Impact Basin / Impact Crater
What is created when a meteorite hits a planet?
When a meteorite hits a planet, it can create a crater, eject debris into the surrounding area, and potentially cause seismic activity. Additionally, the impact can generate heat that can melt surrounding rock and create impact melt rocks.
When a large what strikes earth it can create a crater?
Answ2. Strictly speaking, a meteor is one that is seen burning up in the atmosphere. It becomes a meteorite if it lands.Meteor.
Why is the moons crater circular?
because the objects hitting it would hit then the impact would create a circular shape
