Plate tectonics videos (i.e., plate tectonics videos):
    1. Degree-One Mantle Convection | 0:46: A real supercomputer computer simulation of mantle convection---but for that reason, maybe only crudely like the real thing. Good for the classroom.
    2. The Earth 3D Convection currents & tectonic plates | 1:05: Good for the classroom.
    3. mantle convection cells and continental drift.wmv | 0:45: OK, but Scottish: the narrator is Iain Stewart (1964--). The animation assumes whole mantle convection. Less good for the classroom.
    4. Continental drift animation centred on the UK | 0:45: Continental drift, the last 450 Myr. Authoritative from Cambridge Earth Sciences. Good for the classroom.
    5. How Earth Will Look In 250 million Years | 2:06: Cute, but yours truly does NOT know how authoritative it is. Good for the classroom as slow TV.
    6. Continental Drift Theory Video PART 1 | 5:45: OK, but a bit slow-going and too long for the classroom.
