Eli5, why does earth have way less craters then almost any other planet in our solar system?
In: 7
Naturally-occurring craters are typically caused by debris from space that survives to impact the surface of a planet.
Planets with an atmosphere will have fewer craters because debris burns up before it can reach the surface.
Fast moving debris entering Earth’s atmosphere must withstand intense heat caused by friction with the air.
Most or all of the debris burns away before it can reach the planet and make a crater.
