Oceanic Crust - what is it all about?

Over 70% of the rocky surface of our planet (although most of
this is underwater) is made up of oceanic crust.  This
crust, along with the upper mantle make up the oceanic tectonic
plate material.  Oceanic crust is unique - and this episode
explains the features of this type of crust.


This is essential listening for students learning about Plate
Tectonics!
