1Scientists hypothesize that Earth's [blank_start]seven[blank_end] continents were once connected as a single landmass, called a [blank_start]supercontinent[blank_end]. This landmass ,called [blank_start]Pangaea[blank_end], which means "all land", began slowly shifting apart about [blank_start]200[blank_end] million years ago.
The main proponent of this theory was [blank_start]Alfred Wegener[blank_end]. Wegener hypothesized about the existence of Pangaea because of geologic evidence and the way some continental coastlines fit together like [blank_start]jigsaw[blank_end] pieces.
Wegener used evidence from two fossils. [blank_start]Mesosaurus[blank_end] and [blank_start]Glossopteris[blank_end]. Mesosaurus was a reptile found in South America AND [blank_start]Africa[blank_end]. Mesosaurus lived in [blank_start]freshwater[blank_end] and on land and could not have swam between the [blank_start]continents[blank_end]. Glossopteris is a fossil [blank_start]fern[blank_end] that once flourished in warm tropical climates. It has been found in [blank_start]Africa[blank_end], Australia, India, [blank_start]South America[blank_end], and Antarctica. Both of these fossils suggest that Africa and South America were once [blank_start]joined[blank_end], as were the other continents.
Rock Structures also support the idea of Pangaea. Parts of the [blank_start]Appalachian[blank_end] Mountains of eastern [blank_start]United States[blank_end] are similar to the mountains found in Greenland and [blank_start]Western Europe[blank_end]. Furthermore similar [blank_start]folded[blank_end] rock belt are found where [blank_start]Africa[blank_end] and South America were once joined.
Glacial deposits and grooved [blank_start]bedrock[blank_end] in southern parts of South America, Africa, India, and Australia suggest that these areas were connected and covered by the [blank_start]glaciers[blank_end].
Finally, radiometric dating has shown that rocks of [blank_start]similar[blank_end] age and type can be found where South America and Africa were once [blank_start]joined[blank_end].- Aseven
