Plate boundaries
Compare spreading, subduction and sliding. Change the plate speed and inspect the exposed rock layers.
The model and its limits
Kinematic section, not a stress or mantle-flow solver. 1 cm/yr = 10 km/Myr. Depth is travel × sin(dip); layer thickness follows √age. Geometry is schematic.
Equations used in the module
Equations s = v t; z = s sin δ; L ∝ √age
