How Life Drives Mountain Building on Earth & What This Means for Space Exploration | GEO GIRL
Can mountains on other planets and moons help us search for alien life? A 2021 study (Parnell & Brolly, 2021) showed that mountain building on Earth has been, at least in part, driven by life on Earth. But how does life help build mountains?? In this video, I talk about the history of mountain building on Earth and how life has contributed to mountain formation throughout geologic time. Hope you enjoy! ;D 0:00 How Mountains Form on Earth 2:02 Increase in life & C production 3:01 Higher C content of old vs young rocks 3:57 Can C deposits cause mountain building? 5:50 Organic C in ancient mountains 7:33 This C continues to build mountains 8:45 Is life required for mountains to form? 10:15 Were there mountains before life? 11:32 Main driver of tectonics & mtn building 12:10 Are mountains a sign of life? 14:55 Is Plate tectonics required for life?
