UK6oG1Piq-c a-journey-to-the-earths-interior A Journey to the Earth's Interior After thousands of years of investigating our planet we are still puzzled by many things. And now I invite you on a brief expedition where we will take a look at some of the most unusual places and phenomena on the planet. VKq0pr4rbRs what-did-pangaea-look-like What did Pangaea Look Like? Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago). 3FoSAHk7DMA what-would-a-journey-to-the-earths-core-be-like What Would a Journey to the Earth’s Core Be Like? What’s the most exotic destination you’ve been to? Hawaii? Australia, Hoboken, New Jersey? QUd1XColj-s whats-under-antarcticas-ice-sheets What's Under Antarctica's Ice Sheets? Many of us know Antarctica as a land of ice and not much else. But hidden beneath the miles of glaciers and ice sheets lies a landmass that was last exposed 40 million years ago. What does this land look like, and what could we expect to find if we are still around to see what's under Antarctica's ice sheets. i8Zo1_FN6xw naked-science-colliding-continents Naked Science | Colliding Continents How were the continents formed? f5ExuqB6SJI geology-12-earthquakes-and-earths-interior Geology | 12 - Earthquakes and Earth's Interior This video is my lecture on Earthquakes and Earth's Interior MeAz8An80ro geology-11-metamorphic-rocks Geology | 11 - Metamorphic Rocks This video is my lecture on metamorphic rocks.
