Noticed these near perfect lines that flow along a rock face in Pembroke. They continue all the way down to the coast but became fainter as they do. Do they have any geological or historical significance and if so how?

  1. Not a geologist, but from the little I know those are layers of rock (most maltese rocks were created through sedimentation) that for some (natural/geological) reason (like landslides) end up vertical from horizontal. Due to weathering (edit: or other forces exerted on the rocks) they end up breaking up in near perfect lines down the weakest sedimentation layers. Use google limestone sedimentation and weathering.
