What planet has craters made by meteorites?
Mercury, Venus, Earth, and Mars all have impact craters.
Is mercury covered with craters molten iron or oceans?
Mercury is covered with impact craters, similar to Earth's moon. It also has a large iron core, which creates a magnetic field. There is no evidence of oceans on Mercury due to its extreme temperatures.
What does a planets like mercury have more craters than the earth?
In the earliest days of our solar system (which I like to call the "Demolition Derby epoch") earth probably had as many or more craters than Mercury did. But earth developed weather, which over the millennia, wore the craters away. Mercury never had weather, so it's craters remain untouched today.
Why does earth lack craters?
Earth does have impact craters, but it has much few than the moon or Mercury and many of them are not readily visible. The main reason is that Earth has many active geologic processes that renew and change its surface, burying and destroying impact craters. If an impact crater on Earth is clearly visible then it probably formed quite recently in geologic history. Many of the impact craters on the moon and Mercury are billions of years old, dating to when the solar system was young and large asteroid impacts were far more common than they are now. Very little of Earth's crust from that time remains intact. By contrast craters on Earth that are tens of millions of years old are not readily visible.
How many impact craters and basins have been found it on earth?

Why do you see impact craters on mercury and the moon but not so much on earth?
Earth has a thicker atmosphere that burns up most of the smaller meteoroids before they can reach the surface, whereas Mercury and the Moon have very thin or no atmosphere to protect them. As a result, these bodies are more vulnerable to impacts from space debris, creating visible craters. Additionally, Earth's active geological processes, such as erosion and tectonic activity, continually reshape the surface and can erase evidence of impact craters over time.
Is mercury and the moon covered with craters on the surfaces?
Yes, Mercury and the Earth's moon are covered with craters on the surfaces
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.
Are there more craters on Mercury and the Moon than the Earth?
The surface of the Earth has been reworked over geological time and this has erased evidence for craters that have existed on the Earth. However all the inner planets and moons have been subject to the same rate of impactors and as Earth is larger, it is therefore likely that Earth has in fact received more impactors (and therefore had more total craters) than the Moon or Mercury. There are more craters now visible on the Moon and Mercury, but there were likely many more on the Earth over the same astronomical time. But craters on Earth have become less visible due to erosion and geologic activity - these processes are much more active on Earth than on the Moon or Mercury, which have less tectonic activity, no real atmosphere, and no liquid water.

Which planet is less than half the diameter of the earth and looks like your own moon?
Mercury. Its surface is covered with impact craters similar to those on Earth's moon. Its diameter is approximately 4879 km while Earth's is ~12,742 km
Which planet has craters like the earth moon's?
Mercury
Common between mercury's surface and earth's moon surface?
The surface is pitted with meteor impact craters. See related links for pictorial
