With reference to the distribution of petroleum in the world, consider...
- Petroleum is also called ‘black gold’ or ‘liquid gold’. It is second to coal in terms of sources of energy. It is an essential source of energy for all internal combustion engines in automobiles, railways and aircraft. Crude petroleum occurs in sedimentary rocks of the tertiary period. It is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and subjected to intense heat and pressure. Hence statement 1 is not correct.
- Petroleum (and natural gas) are born and accumulate in the sedimentary mantle of the Earth. Small amounts of these hydrocarbons are present throughout the mantle, but large accumulations are encountered less frequently. About 600 sedimentary basins, characterized by oil and gas occurrence, are found on the Earth.
- Unlike coal, Petroleum is not distributed evenly around the world. More than half of the world’s proven oil reserves are located in the Middle East. Following the Middle East are Canada and the United States, Latin America, Africa, and the region occupied by the former Soviet Union. Each of those regions contains less than 15 percent of the world’s proven reserves. Hence statement 2 is not correct.
- The two largest classes of fields are the super-giants, fields with 5 billion or more barrels of ultimately recoverable oil, and world-class giants, fields with 500 million to 5 billion barrels of ultimately recoverable oil. Fewer than 40 supergiant oil fields have been found worldwide. The ArabianIranian sedimentary basin in the Persian Gulf region contains two- thirds of these supergiant fields. The remaining super-giants are distributed as follows: two in the United States, two in Russia, two in Mexico, one in Libya, one in Algeria, one in Venezuela, and two in China.

With reference to the distribution of petroleum in the world, consider...
Explanation:
1. Crude petroleum occurrence:
- Crude petroleum is not found in metamorphic rocks of the tertiary period. It is mainly found in sedimentary rocks.
- The formation of crude petroleum occurs over millions of years through the decomposition of organic matter under high pressure and temperature in sedimentary rocks.
2. World's proven oil reserves:
- More than 90% of the world's proven oil reserves are indeed located in the Middle East region.
- Countries like Saudi Arabia, Iraq, Iran, Kuwait, and the United Arab Emirates are known to have vast oil reserves.
- The Middle East region is a major player in the global oil market and has significant geopolitical influence due to its oil reserves.
Therefore, based on the above explanations, both statements given in the question are incorrect. Crude petroleum is primarily found in sedimentary rocks, and the majority of the world's proven oil reserves are concentrated in the Middle East, not in metamorphic rocks of the tertiary period.
