Plate Tectonics Simulator: Lithospheric Boundary Dynamics

An interactive geological model illustrating how convergent, divergent, and transform plate motions deform Earth’s crust, trigger earthquakes, and forge mountain ranges.

Interactive cross-sectional diagram of two tectonic plates floating above the upper mantle asthenosphere. Users can select between convergent, divergent, and transform boundaries, advance through three stages of geological stress and deformation, and read comprehensive descriptions of seismic activity and resulting landforms.
Convergent Boundary Cross-SectionGeological simulation of a Convergent Boundary showing Initial Convergence & Ocean Trench. The dense, water-saturated oceanic plate pushes against the thick, buoyant continental plate. Gravitational pull and slab pull force the oceanic slab downward into the asthenosphere.ASTHENOSPHEREOceanic Plate (Dense)Continental Plate (Buoyant)TRENCH

Geological Landforms & Outcomes

  • Deep Oceanic Trench along subduction zone
  • Partial melting producing volcanic mountain arcs
  • Deep Wadati-Benioff seismic zone with powerful megathrust earthquakes

Real-World Case Study

Location: Cascade Subduction Zone & Andes Mountain Range

Plate Motion: Plates move toward each other (compressional stress)

Crust Type: Dense Oceanic Crust meets Buoyant Continental Crust

Initial Convergence & Ocean Trench

Plates Colliding (Subduction & Mountain Building)

The dense, water-saturated oceanic plate pushes against the thick, buoyant continental plate. Gravitational pull and slab pull force the oceanic slab downward into the asthenosphere.

Seismic & Geologic Activity: Moderate compressive earthquakes along the shallow plate boundary.

Pedagogical Note: This simulation is a simplified educational representation of lithospheric geodynamics. Real plate boundaries involve complex 3D convection plumes, mantle geochemistry, and millions of years of gradual deformation.
