Question

• A. Absence of air
• B. High temperature
• C. High pressure
• D. All of the above options are correct.

Answer 1

Answer: (D)

All of the above options are correct.

Absence of air, high temperature and high pressure transform the dead organisms into petroleum and natural gas. Petroleum was formed from organisms living in the sea. As these organisms died, their bodies settled at the bottom of the sea and got covered with layers of sand and clay. Over millions of years, absence of air, high pressure and high temperature transformed the dead organisms into petroleum and natural gas.
