Tectonic Landscape Modeler

Model how constructive forces (uplift, volcanism) and destructive forces (weathering, erosion) operate at different spatial and temporal scales to form Earth's continental and ocean-floor features.

Constructive vs. Destructive Forces

Earth's surface is a constant battleground. Constructive mechanisms like tectonic uplift (orogeny) and volcanism build landmasses up, driven by internal heat. Destructive mechanisms like weathering, river erosion, and mass wasting tear landmasses down, driven by gravity and the water cycle.

Spatial and Temporal Scales

These processes operate at vastly different scales. Tectonic uplift might raise a mountain range by a few millimeters a year over millions of years (long temporal scale). A landslide (mass wasting) can alter a mountainside in seconds (short temporal scale). Both shape the final landscape.
