Core Geology DVD

30 minutes, Produced in 2007

Not since the discovery of gold in 1848 has the understanding of the world's geology been more important to the welfare of the nation.

Throughout history the rise and fall of civilizations has been propelled by the abundance and scarcity of valued resources. At no time has this been truer than in the 21st century. Whether it is the search for oil or silicon to make microchips or uranium to run power plants, the search is directed by geologists. In Core Geology, the building blocks of this most contemporary science are laid out in a logical order, including the meaning of the fossil record.
