LET US REVISE:
a. Briefly mention how petroleum is obtained?
is being obtained from the sedimentary rocks. It is formed from the
organic decomposition of the remais of marine products deposited in
silt or mud inside the sea bed for a long period of time. The pressure
due to overlying sediments along with the movements of earth converts
the silt and mud into rock and the afore-originated pores with the rock
are occupied by the organic remains. High heat and pressure changes
those organic remains into mineral oil and natural gas.
b. Why does India have to import mineral oil? (2)
* Less reserves as compared to production.
* Increasing number of automobiles and industries day-by-day.
* Lack of technology and capital for exploiting the present reserves.
c. Why petroleum is called mineral oil? (2)
word ‘petroleum’ has been derived from two latin words ‘petro’ meaning
rock and ‘Oleam’ meaning oil. It is obtained from rocks, particularly
sedimentary rocks of the earth. So it is called mineral oil.
