Scientists detect signs of hidden structure inside Earth's Core

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our knowledge of what lies beneath Earth's crust has been inferred mostly from what volcanoes have divulged and what seismic waves have whispered. From these indirect observations, scientists have calculated that the scorching hot inner core, with temperatures surpassing 5,000 degrees Celsius, makes up only 1 per cent of Earth's total volume.
