Here is a NASA map of which direction the plates are moving – important to my theoretical proposal by Sage Goddard in his class. Luckily my research is proving out my theory! (Ahem, his theory).
Here is a Place Holder for a video I found – the one I am keeping track of is Number 48 from a series of 85 from KhanAcademy, talking about how convection makes the plates move. You may have to search to number 48 or specifically search the title “Plates Moving Due to Convection in Mantle”. You Tube has the series. I don’t want to lose track of it.
Number 50 is “Compositional and Mechanical Layers of the Earth”. Also important to my theory.
