Answer to Question 1

Gravimeteruses the gravitational pull of the oil.
Magnetometermeasure s the magnetic pull of the earth.
Seismographuses sound waves to locate oil.
Taken together, these devices indicate likely deposits of oil deep underground and are used to determine likely
drilling sites.

Answer to Question 2

As plants (and to a lesser degree animals) died and decomposed, they formed thick deposits of organic matter. As
soil and rocks were deposited over the organic deposits, pressure was exerted on the materials from the weight,
forming oil and natural gas.
