“Sunken relics, ghostly shipwrecks, and lost cities aren’t just wonders found in fictional adventures. Beneath the ocean’s surface, there are ruins where people once roamed and shipwrecks loaded with artifacts from another time.” My latest TED Ed lesson explores underwater archaeology from the coast down to the deepest depths, identifying the types of sites found at different zones and explaining the processes that got them there.

This is the second lesson that I have made with TED Ed, the first being Real Life Sunken Cities.
