geodynamic
jee-oh-dy-NAM-ik
Definition
Relating to the forces and internal processes—such as heat, mantle flow, and plate movement—that shape and reshape the Earth's physical structure over geological time.
Etymology
Derived from the Greek roots 'geo' (Earth) and 'dynamikos' (powerful/forceful). It combines these to describe the study of the dynamic, ever-changing forces acting upon the Earth's crust and interior.
In the news
In this article, the term describes computer simulations used to reconstruct how mantle movements and tectonic forces uplifted the Antarctic continent. These models help scientists understand the physical mechanisms that created the high-elevation landscape necessary for ice to accumulate.
Antarctica developed a continental-scale ice sheet 34 million years ago while Earth was about 5°C warmer than today — helped by slow-moving mantle waves that had spent more than 100 million years lifting its interior high enough for permanent ice to surviv
