Carboniferous Ice Age and Its Effects

The video explores the Carboniferous period, focusing on the Pennsylvanian Ice Age and its indirect link to giant insects. It discusses the formation of Pangaea, the causes and evidence of the Ice Age, and its biological impacts, including a mass extinction. The video also explains how high oxygen levels led to giant insects and concludes with the factors that ended the Ice Age.
