What evidence do scientists have to support the existence of Pangaea?

What evidence do scientists have to support the existence of Pangaea?

Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart.

What evidence exists to support the existence of Pangea quizlet?

Fossils of identical organisms were found on several continents, indicating the continents were once joined. Late Paleozoic sedimentary rocks often contain extensive coal seams that were used to support the existence of Pangaea.

Which two pieces of data would support the idea that Pangea once existed?

Answer: The real answer is B (Fossils of one plant species found all over one continent) and D (Similar mountain formation in North America and Europe).

What broke apart Pangaea?

During the Triassic Period, the immense Pangea landmass began breaking apart as a result of continental rifting. A rift zone running the width of the supercontinent began to open up an ocean that would eventually separate the landmass into two enormous continents.

What broke Pangea?

About 180 million years ago the supercontinent Pangea began to break up. Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle.

What ocean formed when Pangaea broke apart?

Atlantic Ocean

Will the continents become one again?

Just as our continents were once all connected in the supercontinent known as Pangea (which separated roughly 200 million years ago), scientists predict that in approximately 200-250 million years from now, the continents will once again come together.

Was all land on Earth connected?

This giant landmass known as a supercontinent was called Pangea. The word Pangaea means “All Lands”, this describes the way all the continents were joined up together….Earth’s Tectonic History.
