What is liquid gold? Petroleum or mineral oil is called liquid gold. Why?

Oil-exporting countries earn a lot of foreign exchange by selling this oil.

Petroleum extracted from mines is refined in various processes. Then it runs as many cars, ships, aircraft, engines, factories in the world.

The use of liquid gold began about a hundred years ago. It has changed the face of the earth. Lord Playfair was the first to show that petroleum extracted from mines could be used for refining. There are many oil mines in Saudi Arabia, Kuwait, Russia, Iran, Iraq, USA, Venezuela etc.
