What makes the Earth work, and how do we know that our modern concepts are completely factual? California’s earthquakes and thermal springs, such as occur locally in Sonoma County, were the focuses of scientific studies that helped to resolve those questions. Geology combined with physics (Geophysics) developed inventions for detecting earthquake waves, thermal variations, and density differences that together revealed the Earth's internal structure and compositional differences—and eventually confirmed the processes that created and still modify oceans and continents. This talk will describe the signal discoveries that led to worldwide acceptance of mobile Earth (Plate Tectonics) concepts. This is the second in a series of three talks Dr. Nielson is presenting this spring. The last one will be "From Earth to the Moon and Back Again" on April 26.
