Firebenders rise with the Sun and waterbenders draw energy from the moon, so where do earthbenders get their power from? Well... obviously the answer is California, USA. Today we're looking into the literal worldbuilding of Avatar and The Legend of Korra. To understand the SCIENCE of earthbending, we're consulting the Avatar Bible, vacationing to the West Coast, and working with cartography experts to study the fascinating geographical field of plate tectonics. As far as Avatar Theories go, this video has it all! Who is the best earthbender? How did Toph invent metalbending? What secret lore was lost to Avatar history? Realistic Avatar maps, the San Andreas Fault, the Rise of Kyoshi, and world-ending earthquakes... Matpat would be proud!
