The carboniferous period saw a mass extinction of what type of life and why?
Land Animals: because pangea was forming and all the geological activity only impacted land animals
Land animals: because oxygen levels lowered in atmosphere and didn't reach ocean life
Ocean life:because oxygen levels in the ocean changed causing only ocean life to die.
Ocean Life: because pangea was forming and the sediments made the ocean water unlivable
How did the formation of pangea cause reptiles to form?
Pangea covered so much space on the planet that the oceans became ponds.
Pangea's volcanic activity heated up the environment enough for reptiles
Amphibians couldn't survive in the ocean so they developed into reptiles
Pangea is so large that the middle became dryer allowing reptiles to form
