What planet has craters made by meteorites?
Mercury, Venus, Earth, and Mars all have impact craters.
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?
Earth Impact Database, a website concerned with over 170 scientifically-confirmed impact craters on Earth.
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.
Scientists believe that the earth once looked like mercury?
what happems to all those craters on earth
Why do you see impact craters on mercury and the moon but not so much on earth?
Because there are not as many impact craters that you can see very well on Earth like there are on the Moon and Mercury.

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.
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

Common between mercury's surface and earth's moon surface?
The surface is pitted with meteor impact craters. See related links for pictorial
Which planet has craters like the earth moon's?
Mercury
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.
Why is the surface of mercury covered with meteor impact craters while earth surface has relatively few craters?
Earth is a geologically active planet, the heat in its core moves the Earth's surface around and creates new oceans and mountains over time and these are eroded slowly by the processes going on in and caused by Earth's atmosphere. On Mercury there is no atmosphere and the planet no longer has a hot core causing its surface to be reworked, Thus the craters made in Earth's surface are erased over time while those on Mercury are not.
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.
