How Plate Tectonics Was Discovered
- fanf2 3y agoThis is a documentary from 1970 explaining the how the evidence was gathered and how the theory was developed. At that time it was only 2 years old! There’s a good deal of excitement from the scientists, and a splendid collection of the practical models they used to demonstrate it.
- simonblack 3y agoBack before about 1960, most of us remarked on how many of continents fit together very nicely. But it was just an interesting factoid. Even as a ten-year-old, that was what I had noticed myself. It was around then, that I heard about Wegener from a History(!) teacher. It wasn't till the IGY in (IIRC) 1957, that the mid-Atlantic ridge was discovered and that was the catalyst that 'proved' that the theory might just have some truth in it.
