Plate tectonics can drift continents and push up mountains, but what drives the plates? This is an insiders account of how we answered questions posed over two centuries ago, and completed geologys quest for a driving mechanism. Forging through confusing evidence, apparent contradictions and raging debates we arrived at not one but two mechanisms: sinking plates and rising plumes.

Dr. Geoff Davies is a retired geophysicist with degrees from Monash University in Australia and the California Institute of Technology. He was a postdoctoral fellow at Harvard University and held several academic positions, concluding at the Australian National University. He has published two scientific books and over 100 scientific papers. His work focusses on mantle dynamics and related topics, as well as the interaction of mantle convection and the thermal evolution of the earths interior, which controls the tectonic evolution of the earth.
