According to A Short History of Nearly Everything, plate tectonics is a very new idea, within my lifetime new. I forget the numbers, but the author states that by the 1980s a large minority of geologists still didn’t believe in it.

He prefaces this with stories of naturalists being puzzled over the age of the Earth. They couldn’t explain what they had observed if the Earth was only 10s of millions of years old.

Awesome book BTW. It’s a history of science, what we knew and when and how we figured it out.
