The Theory of Continental drift proposed by Wegener was strengthened by the fact that Fossils of Glossopteris were found on many continents that were now far apart. Fossils of Glossopteris were found on Australia, India, South America and Africa, suggesting these were all close to Antarctica once.

There is a phenomenon called 'magnetic banding' where rock preserves the orientation of the earth's magnetic field at the time it's created at constructive plate boundaries. The earth's magnetic field flips every so often in geological history, so we see bands of rock in the sea floor with alternating magnetic signatures. This indicates that the seafloor has spread and made new rock over time, and so the continents associated must have spread (and met in the middle at some point in the past.) Similarly, we see volcanism and earthquakes happen at destructive plate boundaries, suggesting plates are drifting and being pushed under one another, indicating that overall the plates are moving. Now we can put GPS markers all over the world and use satellites to accurately show how much certain plates have moved in a particular timeframe.

Similar plant and animal fossils are found around different continent shores, suggesting that they were once joined.

e.g The fossils of Mesosaurus, a freshwater reptile rather like a small crocodile, found both in Brazil and South Africa

Hope this helps :)

Glossopteris floral, a fern, was used.

Both plant and reptile fossils helped to support Wegener's theory. I have included three links. You can find much more information on plate tectonics by doing a search on fossils and plate tectonics. Fossil evidence is only one area that supports plate tectonics.

A plant fossil called glossopteris was found on numerous continents true or false?

True


What evidence do the scientists have to support the idea that continents were once a large landmass?

The evidence scientists have are fossil clues, plant clues, climate clues and rock clues. Fossil clues supported the idea because a certain fossil the Mesosaurus was found in two continents on opposite sides of the Earth and the only reason for that is if the lands came together at one time. Plant clues support the idea the same way fossil clues do, like the plant called a Glossopteris was found in different areas around the world. Climate clues support the idea because some of the fossils and plants from warmer climates were found in the Arctic. That explains why there are glaciers in tropical areas. Lastly rock clues support the idea because if the continents were once connected at one time, then the rocks that made up the continents should be in the same locations where they were joined.


What evidence supports the idea that all the continents were once joined together?

There are two main pieces of evidence: Animal and plant species are present on separated continents. The continents fit together like a puzzle.

It was a land plant.

What is the fossil that was found on different continents and was used to support the theory of continental drift?

There was a lot of fossils that were found but the most interesting one is the plant called Glossopteris, it was the only seed-fern plant fossil found.


What evidence may be cited to prove that there once existed a supercontinent?

Same fossils of a plant on different continents.


What three sources of information do scientist use to learn about ancient climates?

The scientists use fossil and plant remains that have been found in continents and this process of the continents moving is known as uniformitarianism.


What evidence is there that the present-day continents were once a single land-mass?

The continents fit together like a puzzle. There are also animal and plant species (extinct or extant) present on continents that are not physically connected.
