Where it all began.

 

Gondwanaland

 
Gondwanaland was named after the glossopteris fern.  The fern is typically found in the seems of permocarboniferous sediments. When the glossopteris fern fossils are correlated between the continents, they become aligned and form the godwanaland continents.  

 

EVIDENCE THAT THE CONTINENTS WERE ONCE JOINED:

  • Identical plant and animal fossils of the same age have been found in rocks in Africa and South America. This strongly suggests that the two were once joined. For instance the fern 'Glossopteris' can be dated at 270 million years ago and can be found in banded areas of South America, Africa, India and Australia.

 

 

 

PLATES ARE CREATED: In the diagram below you can see that the continental crust is beginning to separate creating a diverging plate boundary. When a divergence occurs within a continent it is called rifting. A plume of hot magma rises from deep within the mantle pushing up the crust and causing pressure forcing the continent to break and separate. Lava flows and earthquakes would be seen.
