Plate Tectonics Introduction

What does the theory of Continental Drift explain?

• Ocean currents move continents around the planet

• Convection works deep within the asthenosphere

• Mid-ocean ridges force tectonic plates to move

• Continents were once together and slowly drifted to where they are today

Where does seafloor spreading take place?

• Convergent boundaries

• The continentals shelves

• Transform boundary

• Mid-ocean ridges

The super continent that existed when all continents were together was named

• Gondwana

• Laurasia

• Eurasia

• Pangea
