Plate tectonics visualised part 1: subduction/converging plates/volcano side-view

I've uploaded a series of four videos I made for my graduation assignment about plate tectonics. As a practical part of this assignment I decided to make stop-motion movies to help visualize people how plate tectonics work.

The text is all in Dutch so here's a little translation:

Opening title:
converging plates: subduction

First still:
pink: plate a
yellow: plate b
red: earths mantle
blue: sky/ocean
black: direction of mantle convection

When one considers the area over which the mantle convection can exert this force (think of the size of the Pacific plate for instance!) it isn't all that remarkable that a plate gets pushed(!) in a certain direction. The fact that some plates override others isn't because the other plate is pulled downward, rather it sinks when colliding due to it's greater density (3300 kg per cubic metre for most oceanic plates as opposed to 2700 kg per cubic metre for continental crust)

How do you know that mantle convection is really happening? This is a guess, and a faulty one, because it takes a LOT of energy to pull down a continental plate under another.

wonderful detail
