I wonder if this new satellite technology will eventually show that the earth is pockmarked to the extent that if resembles the moon? That is, would resemble the moon but for the geologic forces here; absent on the moon?
Thanks for another interesting read.
FGS
The seeming lack of craters was more a psychological problem than a physical one. While erosion changes the look here and there, the surface of the Earth has quite a few craters, and more are bound to show up as more people are looking. Besides Barringer/Meteor Crater in AZ, Shoemaker also proved the Ries Basin in Germany was formed by impact. The dominant force shaping the lunar surface OTOH is impact. Erosion on the lunar surface is due to micrometeorites, which don't reach the surface of the Earth (other than as slow-settling dust).
