ANIMATION: Oil Formation and Trapping
This animation shows the successive stages in the formation of an oil reserve. In View 1, organic material settles, is buried, and is transformed by heat and pressure into oil. In View 2 an oil trap is formed: the area folds into an anticline, and oil migrates and accumulates in the anticline crest. For more information, see Section 14.3 Oil and Gas starting on p.489 and Figure 14.4 on page 490 in your textbook.
Zoomable Art: Power from the Earth
Modern society, for better or worse, uses vast amounts of energy to produce heat, to drive modes of transportation, and to produce electricity (see Appendix B). This energy comes either from geologic materials stored in the Earth, or from geologic processes happening at our planet's surface. For more information, see the Featured Painting on pp.514-515 in your textbook.
