How was the theory of plate tectonics developed? fst!

It was developed by Alfred Wegener around 1912-1915 time frame. He proposed his theory of the "continental drift". He proposed that the continents plowed through crust  of ocean basins. He said that the continents look like a puzzle piece to put together. It's very interesting.

Hope this helped :)

have a great day
