Let's review the geological history of Alberta during the Paleozoic and Mesozoic eras and complete the associated practice questions in the textbook.
Understand the Problem
The text provides a detailed overview of geological periods related to Alberta's history and significant events in Earth's past, including extinctions and the evolution of species and landscapes. It is giving a historical and geological context and suggests review activities related to the discussed content.
Answer
Alberta experienced marine environments during the Paleozoic and alternating marine transgressions and uplifts in the Mesozoic.
Alberta's geological history during the Paleozoic era was characterized by marine environments with sediment deposition, while the Mesozoic era saw alternations between marine transgressions and emerging landmasses.
Answer for screen readers
Alberta's geological history during the Paleozoic era was characterized by marine environments with sediment deposition, while the Mesozoic era saw alternations between marine transgressions and emerging landmasses.
More Information
The Paleozoic era is known for the richness of marine life and significant sedimentary rock formation. In contrast, the Mesozoic era is famous for the dinosaur age and the break-up of the supercontinent Pangaea, impacting Alberta's geology with alternating sea-level changes.
