Cratering & Surface Age Explorer

Investigate why Earth has so few visible impact craters compared to the Moon, despite forming at the same time 4.6 billion years ago. Use the timeline to simulate the Late Heavy Bombardment, and experiment with Earth's geological processes to see how they erase evidence and "reset" the radiometric age of surface rocks.
