1 point What evidence can you give that shows the surface of Jupiter's moon Europa must be relatively young? Europa was not orbiting Jupiter when Galileo observed its moons, but now it is there are thousands of active volcanoes on Europa's surface radioactive rocks from Europa that have been brought back to Earth by our probes show that Europa is a young moon we see very few craters compared to the surfaces of Callisto and Ganymede the interior of Europa is made of metals like iron and nickel.
