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 Meteor Crater in Arizona was formed around 50,000 years ago when a large meteorite struck the Earth. It is one of the best-preserved impact craters on Earth and is estimated to be around 50,000 years old.
What would have made the craters on Mars?
The craters on Mars are primarily caused by asteroid and meteor impacts. Mars has a thin atmosphere that offers less protection from incoming celestial objects compared to Earth, allowing impacts to create craters on its surface over millions of years.
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.
What meteor would make the biggest crater a big meteor or a heavy meteor or a fast moving meteor?
To put it simply, let's look at the question. Biggest (Radius), heaviest (Mass) or fastest (Velocity) The largest crater would be created by all three combined. Also, the size of the crater would be dependant on the ground it struck. A larger crater would be produced if it were a soft material like sand, whereas granite would only shatter and not make much of an impact. An object with the radius of tennis ball, would create a crater about the size of a tennis ball if dropped from say 50ft A lump of lead the size of a tennis ball would make a larger crater from the same height. A bullet travelling at 3,200 fps would make a small crater, but much larger than its initial radius or mass. So what would you rather be hit by? a) A large sheet of foam travelling at 10mph (Radius) b) A truck travelling at 5 mph (Mass) c) A bullet travelling at 3,200 fps. (Velocity) d) A bullet thrown at you (Low velocity) So, there is now way to answer the question, as all three are dependant on one another. An object with a large radius but low velocity will not make a larger crater than a massive object with a high velocity. Ditto, a massive object with low velocity will not make a larger crater than a bigger object with high velocity.
Why do some planets have craters?
The shape and size of a crater is dependent on the speed, size, and direction of the object that made the crater. Try tossing some big and little rocks or balls into some soft dirt or sand and see what happens!

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 what do they create?
When meteorites or other objects strike the Moon, they create impact craters. These craters vary in size and shape depending on the size and velocity of the impacting object. Over time, the continuous bombardment has formed the cratered surface we see on the Moon today.
When objects hit the moon they created craters or?
When objects hit the moon, they create craters due to the impact of the collision. The energy from the impact causes the surface material to be displaced and ejected, leaving behind a depression in the surface known as a crater.
What would have made the craters on Mars?
The craters on Mars are primarily caused by asteroid and meteor impacts. Mars has a thin atmosphere that offers less protection from incoming celestial objects compared to Earth, allowing impacts to create craters on its surface over millions of years.
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
When objects hit the moon what are they called?
Objects that hit the moon are typically referred to as meteoroids or asteroids. When they reach the moon's surface, they create impact craters.
What kind of feature might be formed on Earth if a large meteorite reached its surface?
A large meteor strike on the earth might cause a crateron the surface. If it struck the water, it may leave a bit of a crater in the sea floor, depending on the size and velocity and composition of the meteor and the depth of the sea where it impacted. If it hit land, there'd be a big "dent" in the ground where the missle and the blast of impact gouged it out.
What happens after a meteor hits the moon?
When a meteor hits the Moon, it can create a crater upon impact due to the force of the collision. The size of the crater and the extent of the damage depend on factors like the size and speed of the meteor. Over time, the crater may be gradually eroded by other impacts or lunar geological processes.
