About TectonicForge Play
How it works
TectonicForge turns Earth science into things you do — build, tap, read, and reason — not just facts to memorize.
- Earth Interior — tap the layer in a cross-section, from the thin crust down to the solid inner core, that matches each clue.
- Plate Boundaries — decide whether plates are pulling apart, sliding past, or colliding, and name the landform it builds — ridges, mountains, trenches, and island arcs.
- Seismic Station — see which wave arrives first, then read the gap between the P- and S-waves on a seismograph to work out how far away a quake struck.
- Volcano Lab — predict how a volcano erupts from its magma: silica and dissolved gas decide everything from a gentle Hawaiian lava fountain to a towering Plinian ash column.
- Hazard Engineer — choose the safest building design and warning system for each earthquake and volcano hazard.
- Stress & Slip — load a locked fault and feel the rock bend and store energy until it snaps back all at once. That build-up-then-release is elastic rebound — the real reason earthquakes happen.
- Concept kits — 16 short question rounds, from “what is a tectonic plate?” up through earthquakes, volcanoes, hazards, and advanced synthesis.
Our privacy promise
TectonicForge Play is free, works offline, and collects nothing. No accounts, no ads, no tracking, and no data ever leaves your device — your level and streak are saved only in this browser.
Meet the cast
A team of characters brings Earth's engine to life — each one stands for a piece of how the planet works, from its molten layers to the plates, quakes, and volcanoes at the surface. Find their illustrated stories on the cast page.
Mistakes are part of it
You never lose anything for a wrong answer. A wrong guess just explains what you were looking at and points you to the right idea next time — that’s how real science works.
