Come with me on a subterranean tour all the way from the rocky crust where we live through the layer known as the mantle to the wild half-solid/half-liquid core of the Earth. We’ll also be stopping by a newly discovered underground ocean. Let’s go!

The continental crust–the stuff found under land–can be up to around 50 miles thick; while the oceanic crust–the stuff under our oceans–is around four miles thick. But let’s see what lies below that.
