Which object in the solar system is a frozen mass of ice or dust?
i believe that the answer to that aught to be either comet or asteroid
Can an asteroid hit Mercury?
Yes. All the planets can and have been hit by asteroids.
Which layer of the atmosphere protects Earth's surface from being hit by the most meteoroids?
The mesosphere protects the earth from most meteoroids.
What is the difference between planets inside the Asteroid belt and planets outside?
The planets inside the steroid belt will get hit and the other planets will not.
Is it possible planets collide with another?
In the early stages of planet formation, planets did in fact hit other planets. Mercury, Earth and Uranus all have signs of planetary impacts. Nowadays, the solar system is stable and a planetary collision is highly unlikely without some form of external impetus.
Do asteroids hit other other planets as well as earth?
Yes.
Why do planets like mercury have many more crater holes then earth?
Earth has an atmosphere unlike Mercury. Since Earth has an atmosphere, the meteriors burn up before they hit the ground. Mercury has little to no atmosphere so the meteriors are free to hit the ground and make craters.
Why does mercury have so many craters?
Like the Earth's Moon, Mercury has virtually no atmosphere, and no liquid water. Atmospheres can destroy many incoming meteoroids before they reach the surface. Also, weather, water, and volcanism are the primary means of crater erosion seen on Earth. These are not active on Mercury. The overall number of impacts by meteors may be no more than any other planet; the craters persist because there is no mechanism to rapidly remove them, at least not over the few hundred years during which Mercury has been observed by telescope from Earth.
What layer in the atmosphere protects earth from being hit by meteoroids?
the mesosphere
Why are there craters on the moon and not on the earth?
Because meteoroids hit the moon and when meteoroids come towards Earth our atmosphere burns it away into tiny pieces of rock.
Are meteorite hit other planet?
Meteorites hit other planets all the time. In fact, earth get hit the least (about twice every millenium).
Did the planet mercury GED hit by a raid of asteroids as a young planet?
For sure. All the planets were bombarded by asteroids in the early formation of the solar system
