- 2.1: Lesson 2 Introduction
- In one sense or another, we are all Living on an Island. The continents are buoyant rock masses that are floating in the Earth’s mantle-asthenosphere and surrounded by water at the surface.
- 2.2: Overview
- We need a basic understanding of plate tectonics in order to appreciate how the ocean basins have evolved over geologic time and how they will evolve in the future.
- 2.3: Plate Motion and Activity 1
- Let's do something with Plate Tectonics and ask how fast plates move relative to one another?
- 2.4: Activity 2; Motion Under the Ocean, Hot Spots
- For this assignment, you will need to record your work on a word processing document.
- 2.5: Activity 3: Discussion about recent hot spot research papers
- Now that we are experts on Plate Motions, let's think about how Volcanic Island Chains work and how they can help to understand plate tectonics and ocean process.
