Formation
Formation
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
