Formation
Formation
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
