Question

What is called black gold?
A.Petroleum
B.Natural gas
C.Coal tar
D.Coal

Answer 1

Hint: There are different fossil fuels that are valuable resources and are mainly valued for their usage and their importance. The substance called black gold is found on the ocean bed.

Complete step by step answer:
- The black gold is the other name for “petroleum”. It is called “black” due to its colour and it is valued for its usage as a fuel for different vehicles as well as in different machineries. Its comparison to gold is due to the fact that gold is also a prized possession just like petroleum.
- There is a history behind this. Before the mid-19th century, animal fat or tallow and whale bladder were used as fuel. In the year 1859, retired railroad conductor Edwin L Drake found oil after drilling a well near Pennsylvania.
- After this, western Pennsylvania became an important oil-producing area and petroleum products such as kerosene replaced whale bladder in the lamps. During the era of the 1900s, two major regions in the US, Texas and California, became leading oil-suppliers to meet the new global demand for gasoline to run the automobiles.

Hence, the correct answer is option “A”, petroleum.

Note:
Similar to petroleum being called “Black gold”, coal is also a fossil fuel but it is not as pricey or worthy as petroleum. The main reason for this is the time required for the formation of the petroleum. The formation of petroleum requires special conditions, too hot conditions lead to the formation of natural gas instead of petroleum.
