If the moon has loads of crators, who come we weren't hit?

Yeah, right - we're on the moon's doorstep, yet we're a groovy planet, and nice and stuff, revolving, not a care in the world.

Yet the moon is full of crators, hammered over time by massive rocks thudding into it at vast speed.

Why didn't those self same rocks hit earth? Yeah a know a few thousand did, but not to the extent the moon was.

The moon's so battered, it either needs frying with chips or panel-beaten.

If U trust science the Earth was even more hammered than the Moon, beeing bigger and easier to hit- but beeing bigger also ment that stuff (like ice,water) stayed on the earth and soon we had an atmosphere That stopped all those small objects All craters are hidden nowdays but there a plenty of them All this hammering was in the beginning after a while Saturn sorted us out and the rest was pulled by the Sun

The Earth was pummelled, but erosion has covered up most of the scars. No free water on he the moon means vitrtually no erosion

The Earth was well and truly pebbled by asteroids and meteorites in its distant path and is still bombarded on a daily basis. What stops high velocity pebbles and slightly bigger objects from causing damage nowadays is the thing above us called the atmosphere, which I am led to believe doesn't drift away due to the gravity exerted by the Earths magnetic core.

The moon does not have an atmosphere so continues to be bombarded by spacial rubble.

This is also a problem to satellites, and a technical problem to the guys on the ground, who frequently have to rotate the satellites from time to time in order to attempt to protect them from these fast moving particles.

The earth looking well, with all that beating. More so than some of Mike Tyson's opponents!

Thanks for the replies, very interesting.
