AM Location: Strait of Belle Isle (51° 21' 49.48" N, 56° 58' 48.65" W)
The CCGS Hudson is traversing the Strait of Belle Isle today and I am surrounded by a beautiful landscape that reminds me of the mountains of North Carolina. I am gazing upon the highest mountains in Newfoundland which run along the western side of the island. Gros Morne, Indian Lookout, and Western Brook Peak are just a few of the peaks bursting toward the sky and providing the northernmost evidence of the geologic episode that formed the Allegheny and Appalachian Mountains. The tectonic processes responsible for these mountain ranges occurred over 250 million years ago when the super continent "Pangaea" was being formed. The summery green mountain sides flank the deep gorges that look so similar to the Linville Gorge and Hawk's Bill areas of North Carolina. The similarity ends with the smooth mountaintops found in Newfoundland; smoothed by thousands of years of glaciation during the last Ice Age. (See Newfoundland Mountain photo below.)
Today's Activity: Use an encyclopedia or the Internet to locate information about the super continent, "Pangaea." Pangaea is a Greek term which means "all earth." Based on your research, why do you think Pangaea is a good name for the super continent that formed over 250 million years ago?
Word of the Day: Tectonic
REMINDER: Record today's Sea Surface Temperature (SST) and the Air Temperature on the data table you created from the August 05 journal entry.
