Earth’s Interior Structure and Plate Tectonics Explained #66921 (License: Personal Use)

This educational diagram depicts Earth’s internal structure with labeled layers: lithosphere, asthenosphere, mantle (extending ~700 km deep), outer core, and inner core. Red arrows show convection currents in the mantle and the “slab pull” mechanism where dense oceanic plates sink into the mantle at subduction zones, driving plate motion. The ridge represents divergent boundaries where new crust forms.

Used in geoscience education, textbooks, and online learning platforms to explain plate tectonics and Earth’s dynamic interior; matches user intent for understanding geological processes and Earth system science.
