In the Electric Universe most craters on celestial bodies are scars left by electrical discharges. Two or more filaments in a Birkeland current remove material from a surface as they rotate around the current’s axis. This action leaves a circular depression with steep walls. As the current varies, the depth of excavation will vary, ften producing terraces along the walls.
