There was a time when all the land masses on the Earth were connected, roughly 225 million years ago. Though no part of what is presently known as North America ever touched any part of what is presently known as Europe, the two were very close to one another. In the charts I’ve added at the bottom, you can see how the land masses were originally connected, and how they slowly drifted apart.
WHile the other answer provides some good maps, the statement that “no part of what is presently known as North America ever touched any part of what is presently known as Europe” is incorrect. They were intimately connected; their mountain ranges (the Appalachians, mountains in Newfoundland, southeast Greenland, Ireland, Scotland, and Norway) were one mountain range. And they were connected before that, too.
See previous answer from a week ago.
Yes. According to the Pangaea Theory, approximately 225 billion years ago, all land masses formed a supercontinent. Because of shifting plates, the continents eventually spread apart. Though the Pangaea Theory and plate tectonics were first treated skeptically, today, much evidence exists in its favor.
Evidence of similar species has been found on separate continents, suggesting that they were once connected. Identical fossils have been found on these continents, and even more compelling, identical freshwater fish species have been found on separate continents (according to the American Pageant textbook). Furthermore, matching rock strata has also been found on separate continents.
The following map of Pangaea from modestycatalog.com demonstrates the closeness of the continents:
Notice the shape of modern continents in relation to one another. Their shapes suggest that they were once connected.
