The Earth’s Inner Core is a solid sphere primarily composed of Iron.
Despite its relatively small size as compared to the Earth’s volume,
it plays a critical role in the dynamics and overall functioning of our
planet. Understanding the inner core’s properties, such as
composition and behavior under extreme temperature and
pressure is essential for insights into the thermal evolution of the
planet. Advances in seismology have revealed complexities within
the Inner Core, such as anisotropy and possibly the presence of an
innermost inner core. Combined with geodynamic modeling, I try
to simulate the growth of the inner core to understand the
processes causing its present-day anisotropy to answer questions
like; How is global inner core anisotropy generated during inner
core growth? What caused the present-day orientation of
anisotropy? Our understanding of the inner core not only provides
a window into the past but also offers critical information for
predicting the planet’s geological and magnetic behavior. It also
contributes to broader geophysical models and theories regarding
planetary evolution. |
