Answer:
petroleum is obtained from the crust of the earth.
Explanation:
It is made from the fossils.
A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum has mostly been recovered by oil drilling (natural petroleum springs are rare).

Petroleum is obtained by drilling holes into the earth crust by machines call drilling rigs.
Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria
