Question

· Why are there no craters on Earth? Did all the meteorites miss us? ?

Answer 1

There are some large craters.  Perhaps the biggest is the Yucatan.  Most of the craters are gone because of erosion.  Raindrops will make little craters in mud.  Watch and see how long they last.

Answer 2

There are lots of craters on our planet.

Here is a list:

Answer 3

meteor crater in Arizona

Answer 4

Actually there are many craters on Earth.  You can go to this web site to see where a bunch of them are: http://geology.com/meteor-impact-craters...

  Earth is just as likely to be hit as any other planet, however, most of the meteorites are travelling too fast to make it through our atmosphere without burning up (friction with the air molecules).

   There is a really big crater just off of the coast of the Yucatan pennisula, in the Gulf of Mexico.  Many scientists suspect that the meteorite that made this crater was the one that pushed the dinosaurs to extinction.  

Answer 5

There are many, many craters on Earth.

Meteor Crater in Arizona is only one example.  Other examples include the one in the Yucatan that killed off the dinosaurs and one in Chesapeake Bay (US).

Answer 6

3 answers :

1/ There are many craters as the other answers told you

2/ The earth has an atmosphere, thus, small meteorites, that could cause a crater on the Moon or Mercury or even Mars with its very light atmosphere, are burning when they enter in the atmosphere of the earth. So a lot of meteorites do not reach the ground surface. Only the largest one.

3/ The earth has an atmosphere, again, which is eroding the existing craters very fast. This is the reason while spectacular craters are in desert areas.

A good example is the Ries crater in Germany, it is a very large crater of about 25 km diameter formed by an asteroid of about 1.5 km diameter, 'just' (it is very recent for geology) 15 millions years ago. There is another smaller crater about 40 km west of the Ries crater formed by another meteorite of 150 m diameter at the same period (probably the big one broke in pieces when it entered the atmosphere).

Now, this 2 craters were not seen as craters before 1960 ! In Germany, one of the most populated country of Europe with some of the best geologists !!!

By the way, for info, the impact had the power of 1.8 millions Hiroshima bombs....

Answer 7

There are craters on Earth.

Answer 8

There are many craters on earth.  Some are extremely large.  Many of the craters have been eroded away or filled over time, which is why we see a lot less craters on earth than on the moon, for example.  But the earth has been hit uncountable times.

Answer 9

No, we weren't lucky at all. In fact, most astronomers believe that the Earth was once hit by a mars-sized object, an event which created the Moon. In addition to this major hit, the Earth has been struck by just as many meteorites as all the other moons and planets, and would be completely pockmarked with craters if it weren't for one thing: erosion. The Earth has several very efficient erosion mechanisms which wipe away craters and other geological formations at a very rapid rate. Wind, rain, floods, oceans, ice ages, and plate tectonics all serve to constantly recycle the surface of our planet, wiping away most of the evidence you see in abundance on other moons and planets.
