- Over eons, animal and plant remains fall to the floor of a shallow sea .
- As the oceans recede, the plant material is covered by other sediment layers, such as sand, silt, clay or other plant material.
- The organic material is buried deep in the earth, where partial decomposition occurs in the absence of oxygen.
- Gaseous petroleum products will ÒpondÓ above fluid petroleum products in deposits deep in the earth.
- Natural gas

- Layers of rock often bend and warp into folds or are broken along faults.
- Typical suburface formations in which oil occurs are shown in this cross section of land and coastal waters.

- Anticline
