After putting in lot of fund and manpower ,for years,do you think Plate tectonic works? and can predict with accuracy ,to save some lives?
Is plate tectonic is being developed on the similar guide lines, mentioned by you ?
I may be wrong,but what I feel is ,plate tectonics is developed by looking at the world map and the .matching curves of continents,(rest of the details collected later on.There are chances that,my apprehensions are wrong,if so pl correct)
