Our transcription: Wegener poured over geological maps, maps that showed identical rock types, fossils, and mineral deposits in many different lands.
He was intrigued by what he discovered.
He began to see that certain patterns matched up if you carried them across major ocean basins, particularly in the Southern Hemisphere continents or what we now call "Gondwana," which is split apart into Antarctica, Australia, South America, and Africa.
What he found is that certain plant fossils matched up very nicely on these different continents.
He found certain climatic zones, glaciation zones, or coal bed zones matched up on these various continents, and they didn't make sense with where the continents are today in terms of the current climatic zones.
