If earthquakes happen when tectonic plates press against each other, then do fissures get bigger?
In: Planetary Science
Yes. The fissures you see on these surface are not the edge of a tectonic plate. They are just places where the surface cracked because of movement and pressure.
If the tectonic plates are big sheets of ice, then think of those frissures as just tiny little cracks in a big sheet of ice.
