Why are the oldest rocks found on earth younger than the oldest lunar rocks that Apollo brought back from the moon?
The Earth is still tectonically active and because Earth has weather. The tectonic activity refreshes the crust as some plates are forced under others, removing old rock from the surface, and things like the sea floor spreading and volcanic activity producing all new crust. Additionally, the weather on the Earth constantly works to erode existing crust and wash it into the oceans.
The moon is neither terctonically active nor is there weather. The moon is, in planetary science terms, dead. There is no process to remove old surface rocks and replace with new ones.
