Not ALL Tectonics is ‘Plate’ Tectonics (w/Steven Baumann!) | GEO GIRL
Many people use "plate tectonics" and "tectonics" as synonyms, but they are actually not! In this video I collaborated with Geoscientist & YouTube Science Communicator, Steven Baumann, to cover the differences between tectonics and plate tectonics, and talk about how tectonics worked on Earth before tectonic plates formed! ;D
0:00 Intro
1:38 Plates Are Not Only Crust
4:13 What is Tectonics?
4:42 What Are Plates?
7:16 What is Plate Tectonics?
8:29 What Drives Plate Tectonics?
11:09 When Did Plate Tectonics Start?
14:04 Tectonics Before Plates? (4+ Ga)
16:04 Tectonics Before Plates? (4 – 2.5 Ga)
18:41 Tectonics After Plate Tectonics? (Future)
19:40 Continental vs Ocean Crust
21:37 When Did Continents Form?
23:00 How Did Continents Form?
25:58 What Did Earth Look Like Before Plates?
27:13 Timing of Drip to Plate Tectonics Transition
28:36 Application to Other Planets/Moons
