Although this inner core is white hot, the pressure is so high ... Instead, scientists map the interior by watching how seismic waves from earthquakes are bent, reflected, sped up, or delayed ...

one dataset of seismic waves curiously stood out from the rest," Vidale said. "Later on, I'd realize I was staring at evidence the inner core is not solid." Further, the data showed that the inner ...

Hence, scientists rely on seismic waves generated by earthquakes, to create images of the inner core's dynamics. What did researchers do? By analyzing seismic waves from earthquakes from the 1960s ...

The core itself consists of a solid inner core and a liquid outer core. There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their ...
