Wilson Cycle and Plate Tectonics

Bob Stern, a geosciences professor, explains the Wilson Cycle, a key concept in geology. The cycle, named after J. Tuzo Wilson, describes the formation, evolution, and closure of oceans due to tectonic plate movements. It includes five stages: continental rifting, ocean opening, passive margin development, subduction zone formation, and continental collision. Historical context is provided, highlighting Wilson's contributions to the theory of plate tectonics. The video illustrates each stage with examples like the Red Sea and the Himalayas, emphasizing the dynamic nature of Earth's surface and the recycling of its crust.

Who was the geophysicist that the Wilson Cycle is named after?

• J. Tuzo Wilson

• Alfred Wegener

• Harry Hess

• Charles Darwin

What is the first stage of the Wilson Cycle?

• Continental rifting

• Ocean closure

• Continental collision

• Subduction zone formation

Which ocean is an example of the continental rifting stage?

• Indian Ocean

What geological process occurs when an oceanic plate becomes too dense?

• Mountain building

• Subduction

• Seafloor spreading

• Continental rifting

What happens to the oceanic plate during the subduction process?

• It becomes part of the continental crust

• It is progressively subducted

• It remains stationary

• It rises to form mountains
