Like onions and ogres, Earth is made of layers: the crust, the mantle, the outer core, and the inner core. But what are those layers made of? What animals dig the deepest burrows? How far down have we drilled? And what are those two continent-size blobs that cradle the outer core?
Take this three minute voyage to the center of the Earth with The Royal Society, an animation made in partnership with BBC Ideas. Seismologist and deep Earth expert Dr. Paula Koelemeijer narrates.
Her bio via Futurum Careers, where Dr. Koelemeijer shares free educational resources that teachers can use in class:
“Dr Paula Koelemeijer, a seismologist at the University of Oxford, UK, uses seismic waves to ‘X-ray’ our planet, enabling her to build a picture of the structures that exist deep in the mantle and to interpret these in terms of the processes that have shaped our planet.”
Plus, related from the video: There are many ancient underground cities in Turkey, Elengubu, aka Derinkuyu, being the most famous. Visit another one with the BBC News on TKSST: Matiate, the hidden underground city beneath Midyat, Turkey.
