Continental Drift
November 10, 2011 @ 7:00 pm
In geology, the single most unifying concept is plate tectonics. Doug Cunningham will lead us through the development of the theory, from Alfred Wegener in 1912 to Canadian physicist Tuzo Wilson in the 1960’s. Plate tectonics causes earthquakes and volcanoes. Doug will take us to Turkey, New Zealand, the Hawaiian Islands and Chile – all places where plate tectonics can be observed.
OSFN Indoor Meetings are normally held on the second Thursday of the month at 7:00 p.m. at the Bayshore Community Centre, 1900 3rd Ave E Owen Sound. There are no Indoor Meetings in July and August. Please see the individual event listings below for more details.
We invite speakers with a wide range of expertise from Grey/Bruce and other parts of the province. These evenings are open to the public. The auditorium is open by 6:30. The meeting gets under way at 7:00, and may include brief announcements by other organizations as well as OSFN club activities, club business, social time, nature sightings and reports.
The club also offers a full schedule of outdoor activities during the year. Through these outings, members learn more about the birds, plants, mammals and geology of this part of Ontario. We also keep a protective eye on our precious natural areas.
