An interesting fact: of the Earth's 6,300-kilometer radius, humans have only been able to delve 13 kilometers deep. Why have we only been able to reach 13 kilometers? What lies deep within our planet? What is the Earth's core like, and what will happen if it cools? How do earthquakes work? Should we be afraid of volcanoes? We discussed many interesting things about the structure of the Earth and its formation with Grigory Agranov, a geologist and junior researcher at the Geological Institute of the Russian Academy of Sciences (GIN RAS).
