Asteroids, meteorites or comets are impactors that form impact craters on the Earth and other bodies throughout the solar system.
Obviously, the Earth for instance, has to cross an impactor's orbit or vice versa. The size of the impactor hitting the Earth depends on the type of crater that can occur and also the other factors-
· the velocity of the impactor
· composition of the impactor
· composition of the target rock
· the strength and porosity of the impactor
· angle of impact
· gravity of the target planet

∙ 13y agoDuring impacts, a lot of energy is released and the meteors displace a great deal of the rock/soil that they are impacting against. On atmosphered planets the impacts may generate enough energy to expand the air around them causing the air to expand, creating a shockwave that can displace more earth

Why is the earth not covered with craters?
The earth is not covered with impact craters because weather and geological activity erodes the craters away over time.
Does the surface of moon and earth both have craters?
yes. there are more craters on the moon because no atmosphere protects it from meteors or meteorites, but both the moon and the earth have craters
Why haven't the craters on the moon changed?
On Earth wind and rain cause erosion which changes the surface. The moon has no atmosphere thus nothing to cause change.
Why do you see many impact craters on the moon but not earth?
The Earth has weather patterns that have eroded most of the craters on Earth. The moon has no weather, therefore no erosion.
Which side of the moon has more craters?
The "darkside" or the part of the Moon that does not face the Earth has the most craters.
Why does the moon have crates?
The moon has craters because since it does not have an atmosphere like the Earth does, it is prone to meteors which cause craters.
Who has more craters the earth or the moon?
there are more craters on the moon then on earth
Do craters cover most of the Earth?
No. Earth has relatively few impacts craters.
Were the earth's craters caused by earthquakes?
Earth's craters have been created by Meteorites and Volcanoes.
Does earth have volcanoes craters rings valleys?
Earth has volcanoes, craters, and valleys but not rings.
Can you mention any big pit caused by a meteor?
There is the famous crater in Arizona, known as Meteor Crater or Barringer Crater. It is not actually meteors that cause craters. Meteors are destroyed in the Earth's atmosphere. If they survive the Earth's atmosphere and then land on Earth, they are known as meteorites. So it is meteorites that actually cause craters.
Why is the earth not covered with craters?
The earth is not covered with impact craters because weather and geological activity erodes the craters away over time.
What does the formation of a crater follow?
There are craters formed by asteroids crashing into Earth. There are craters formed by volcanic explosions. There are craters formed by collapses in the Earth's crust.
How many craters Earth?
There are a huge number of craters on the Earth, including very small impact sites. There are about 65 named and documented craters on the planet.
What is the main reason that impact craters on the Moon last much longer than impact craters on earth?
Impact craters on the moon have no water/weather to erode the craters away, but on Earth the erosion erases the craters over time.
What object that is covered with craters orbits the earth?
The moon and Luna are the object that is covered with craters orbits the earth
Are mars craters bigger then Earth craters?
yes its like the moons
