Plate Boundaries and Layers of the Earth

Oceanic crust is

• Younger and less dense than continental crust

• Thinner, younger and more dense than continental crust

• Older, thicker and less dense that continental crust

• Bigger and younger than continental crust

Earth's plates are...

• Never moves

• Moves seldom and very fast

• Moves when it feels like it
