Because of weather erosion. Earth has a thicker atmosphere than the moon, say, which has no atmosphere at all, and thus, no wind, water or rain to wash away the marks left by meteors or asteroids that hit the surface of the planet. Earth is hit by things all the time, but are washed or wiped away quickly by snow, rain, wind, etc.
It is hard to find craters on Earth's surface because the planet's geology is constantly changing due to erosion, tectonic activity, and weathering. As a result, many craters that may have formed in the past have been eroded or covered by vegetation over time. Additionally, Earth's active geological processes can quickly obscure evidence of impact craters, making them difficult to identify.

What is crust?
Crust is the hard outer surface of something, typically the earth or a baked food such as bread or pie. In geology, the Earth's crust is the outermost layer of the Earth's surface, consisting of a variety of rocks and minerals.
Is crust an adverb?
No, "crust" is not an adverb. It is a noun that refers to the hard outer layer of something, such as bread or the Earth's surface.
Forms earth's hard surface?
The Earth's hard surface is formed primarily by the solidified rocks that make up the planet's crust. These rocks can be of various types, including igneous, sedimentary, and metamorphic rocks, which have been created through processes like cooling of magma, deposition of sediments, and alteration of existing rocks under heat and pressure. Over time, these rocks have combined to create the diverse geology of the Earth's surface.
Why are minerals that form below Earth's surface unstable at Earth's surface?
Minerals that form below Earth's surface are unstable at the surface because they are often formed under high pressure and temperature conditions, which are different from the lower pressure and temperature conditions found at the surface. As a result, these minerals can undergo chemical reactions or physical changes when exposed to the new environmental conditions at the surface, causing them to break down or transform into more stable minerals.
What material forms earth's hard surface?
The Earth's hard surface is primarily composed of rocks and minerals. These rocks can be classified into three main groups: igneous, sedimentary, and metamorphic rocks. Igneous rocks are formed from the cooling of molten magma, sedimentary rocks are formed from the accumulation and cementation of sediments, and metamorphic rocks are formed through the alteration of existing rocks under high pressure and temperature.
Why do you see several impact craters on the earth but few on the moon?
There are relatively few craters identified on the surface of the Earth while there are thousands (millions) on the moon. It is hard to find one point on the moon that is not in one crater and there are craters in craters in craters. (See images in related link for Moon.) Obviously, the major reason behind this is that the craters that formed on the Earth eroded over time due to wind, rain and other natural factors which are nearly absent on the moon. Thus Earth's craters disappear over millions of years while the craters on the moon remain for billions of years. (The primary way a crater is made to disappear from the surface of the moon is by having another impact crater formed and the dust and debris from later impacts disturb or destroy or cover the original crater.)
Does earth have many craters?
Yes, they are hard to detect without orbital photography though.
Is the moon soft or hard?
The moon's surface is solid and rocky, so it is not soft. It is covered in craters, mountains, and dust.
If you drop marbles into a pan of sand what would you be simulating about the Moon's surface?
By dropping marbles into a pan of sand, you would be simulating the impact craters that form on the Moon's surface due to meteorite collisions. The craters are created when high-speed objects strike the Moon, displacing the surface material and creating a depression.
If you drop a marble into a pan of sand what would you be simulating about the moons surface?
that it would be like the craters on the moon and that it is very hard.
What is earth hard surface is formed of?
Oh, dude, the Earth's hard surface is formed by a bunch of rocks and minerals that have been hanging out together for, like, billions of years. It's called the crust, and it's basically the Earth's outer layer that we all chill on. So, yeah, it's like a big ol' rock party down there.
Why does the earth have less impacts than the moon?
The answer is that the Earth has more meteoroids hitting it, but most do not survive to impact the surface. The Earth has a protective atmosphere that burns up a lot of meteors. Most others are slowed enough that they don't make a big crater. The ones that do make it to the surface may fall into water, which covers 3/4 of the planet, and these craters are hard to locate. For land impacts, the actions of the atmosphere (rain, winds etc) erode the impact craters, as does geologic and volcanic action. So what we see are only a tiny number of persistent craters that have avoided obliteration. The Moon does not have any of these forces at work, so almost all of the impacts since the moon was formed can be seen on its surface. The major changes in the craters are made by later impacts at the same locations.
How might the moon craters and rilles have formed?
Moon craters are mostly formed by impacts from meteoroids, asteroids, or comets striking the moon's surface. Rilles, on the other hand, are thought to be formed by lava tubes or collapsed lava channels from ancient volcanic activity. Both features give us information about the moon's geological history.
