Birth and death of an ocean

Do you ever wonder why whales and other marine animals are found in the sediments all the way up in the mountains like on the Andes, Himalayas or Alps for example? Or about how our oceans change through time?

In this lesson, we will look at the cycle of how an ocean is born (opens) and how it evolves and eventually dies (closes). This is explained as the Wilson Cycle, named after the Canadian geophysicist J. Tuzo Wilson (1908-1993).

You will learn about how the planet earth works, the Wilson cycle, a bit about plate-tectonics and the boundaries between them.
