 | Plate Tectonics - Lesson 4 - Part 1 of 8 Series made in 1976 - Understanding the Earth by TV Ontario The series host was Dr. David Pearson a renowned English trained, Canadian geologist residing in Sudbury, Ontario. Dr. David Pearson lectured at Laurentian University in Sudbury, Ontario. This series was part of a extension course at Laurentian, i believe from 1976 to 1986. Planet of Man Series -- Jigsaw Fit (30minutes) Host; Tuzo Wilson Plate Tectonics - Lesson 4 - Part 1 of 8 •Continental shift ole ideas -- like ships moving on a oceans •6 major plates divided into series of plates -- comprised both in land and ocean •Plates slide underneath, beside and overtop one another •Andes of South America -- Multiple ranges of north America -- Mountains of the western pacific and Indonesia -- Great Himalayan belt from Asia to western Europe. •Early recognition of the plates -- seismology was used to define narrow belts of earthquake activity. •Earthquake activity followed the boundaries of the plate •Animation of a world map, illustrating the earthquake centers caught by seismological equipment •Also discovered all the active volcanoes were discovered along these earthquake centers •Development of sonar (after WWII) they could now map the ocean floor •What they found is huge mountain ranges, and series of very deep trenches. • Early 60's they discovered the mid atlantic floor they were actually spreading -- sea floor spreading •Thoughts -- if sea floor is spreading?..then there must be some place where the result of the spreading is ending up?... Mountain belts. |

Part 3 Planet of Man Series -- Jigsaw Fit 04-Part3 http://www.youtube.com/watch?v=ZJOrZ1GTvC4 •Scientists in the earlt 70's predicted another San Fran earthquake •Two oceanic plates converge the point of contact is a deep trench •Animation illustration two oceanic plates converging •Molten rock produced from two oceanic plates is granitic •Island Arcs produced -- Japan •"Ring of Fire" •These are violent volcanoes •Earthquake fFootage of the Andes mountain system •Andes mountain is the oceanic plate heads underneath the continental margin of South America. No Island arcs. Volcanic mountain ranges. •Machu Picchu footage monument to a past civilization •Excellent example of converging plates. •Animation showing the formation of the Himalayas •Alps and Pyrenees formed the same way •Animation showing Pangea and the formation of the present day continents |

Plate Tectonics - Lesson 4 - Part 6 of 8 • Illustration showing the cross-section of the Andes -- oceanic plates and continental plates • Illustration showing the cross-section of Japan -- Island arcs • A physical model demonstrating a subduction zone • Illustration showing a subduction zone • Illustration of oceanic ridges -- where lithosphere plates are created • Physical model showing oceanic ridges (spreading ridges) • Illustration of a subduction zones of Japan • Illustration of a subduction zone of the Himalayas in India • Illustration of a subduction zone in Europe |
 | Continental Drift - Lesson 9 - Part 3 of 7 Part 3 Planet of Man -- Beyond a doubt - revolution 9-Part3 Tuzo Wilson •In the 1950's extensive ocean profiling •Mapping the ocean floor, mid oceanic ridge system •Paleomagnetic of the earth's surface. •Harry Hess -- found relationship with mid-oceanic ridge and volcanic activity •Fredrick Vine marine geologist http://en.wikipedia.org/wiki/Fred_Vine explains paleomagnetic reversals. •Tuzo Wilson explaining the origin of the transform fault. .................................. Today, continental theory is superseded by plate tectonics. Continental drift treated only the continents as jigsaw puzzle whereas plate tectonics treats the continents, oceans and the earth's crust as pieces of jigsaw puzzle. These segments are a flashback to part of the development of the current theory |
 | Science on a Sphere: Plate Tectonics and Paleo Animation Science On a Sphere® is a large visualization system that uses computers and video projectors to display animated data onto the outside of a sphere. Said another way, SOS is an animated globe that can show dynamic, animated images of the atmosphere, oceans, and land of a planet. NOAA primarily uses SOS as an education and outreach tool to describe the environmental processes of Earth. This video shows a short piece of Earth's tectonic evolution.

 | The Early Earth and Plate Tectonics The Earth is formed by accretion of spatial particulates and large masses and eventually formes an outer crust. Video follows with speculation of early plates and land masses and their movement through time. |
