Presentation: How the Earth Works by Don Davidson
March 13, 2016 @ 2:00 pm - 4:00 pm$7.50
This illustrated, hour-long presentation will provide a historically oriented narrative linking the scientific thinking on large-scale earth processes such as mountain building from the 18th century to our present understanding of plate tectonics. Topics will include mountain building, continental drift, earth magnetism and seismicity, ocean floor mapping (including ocean ridges and deep trenches), seafloor spreading, hot spots and exotic plate terrains. What makes plates go will also be discussed. While some topics involve complex science topics, the talk will be presented at such a level that it should appeal to listeners of all ages and science backgrounds. Refreshments will be served.
