Jupiter's moon Europa is unique. Underneath its crust, which is made ofice, a layer of liquid water. This bound layer
likely contains more water than there is on Earth. The liquid layer causes Europa to be extremely tectonically active, with
new crust being formed constantly. How does this level of tectonic activity on Kuropa likely reduce the number of Wale
impact craters?
As new crust forms on the surface of Europa, it erases visible impact craters. For instance, along fault lines, some areas of the crust expand while other areas melt and get absorbed into the moon’s interior.
