american and pacific How can you explain the fact that forests grew in Antarctica during the Permian period? The islands formed between _20__and _5__million years ago. What are the processes that drive plate movement? (hint: mantle convection). What was Pangea? a hypothetical continent including all the landmass of the earth prior to the Triassic period when it split into Laurasia and Gondwanaland . Why is it relevant to our understanding of plate tectonics? What does paleomagnetic data tell us about plate movement? Describe differing features of oceanic vs. continental plates. How are subduction zones related to areas of uplift ? How did plate movement shift along the west coast of North America ~15 million years ago? Shifted from a head on collision to a north-south sliding. Why is this shift significant for Channel Island formation? As a transform system of deep cracks and faults, this area produces blocks which become islands. Some rotate in the process and may have been close enough for species of animals to migrate by land bridges. Where on the mainland were the Channel Islands connected before they were
