Earth's crust and upper mantle are broken into sections called?
Earth's crust and upper mantle are broken into sections called tectonic plates. These plates float on the semi-fluid asthenosphere below them and interact with each other at plate boundaries, leading to geological processes like earthquakes and volcanic activity.
