Although it makes a fascinating story, it is not possible
to journey to the center of Earth. Instead, scientists
gather observations at the surface to construct models
of Earth's internal structure. They analyze seismic
data—information from earthquakes—to infer
processes that occur inside the planet.

This model shows material moving
deep within Earth. Materials are marked with different
colors so you can follow their motion.
