Continental Drift & Plate Motion Simulator
Drag two plates and set their velocities to build convergent, divergent or transform boundaries, then watch mountains, rifts and earthquakes appear in a live cross-section.
How to use: select Plate A or Plate B and set its velocity, or use the "Force convergent/divergent/transform" buttons. Watch the map and cross-section update live, then try the Challenge tab for guided goals.
Challenge 1: build a mountain range
Convergent boundaries push crust upward. Set the plates so they collide (a convergent boundary) and keep them going until the mountain elevation passes 500 m.
Challenge 2: trigger earthquakes at a transform boundary
At a transform boundary, plates slide past each other and stress releases as earthquakes. Set nearly equal velocities (a small relative velocity) so the boundary stays transform, and reach 5 or more earthquakes in this session.
About the Continental Drift & Plate Motion Simulator
Free continental drift & plate motion simulator. Drag two plates and set their velocities to build convergent, divergent or transform boundaries, then watch mountains, rifts and earthquakes appear in a live cross-section. Drag, change the sliders and see the result live. No sign-up, works on phone and computer. Built for geology, the continental drift & plate motion simulator runs instantly in your browser: change a setting or drag an object and the result updates at once, so you learn by trying things out rather than only reading about them.
Drag two plates and set their velocities to build convergent, divergent or transform boundaries, then watch mountains, rifts and earthquakes appear in a live cross-section. Use it to explore geology ideas at your own pace, then check what you found against the key ideas further down this page.
How to use the Continental Drift & Plate Motion Simulator
- Use the controls to change Velocity (cm/yr, +right / −left). The simulation reacts instantly.
- Pick an option such as Plate A, Plate B to switch modes or load an example.
- Press "Force convergent", "Force divergent", "Force transform", "Reset to defaults" to start, reset or change what is happening.
- Where you see a glowing handle, object, weight or atom, drag it with your mouse or finger. Everything responds in real time.
- Watch the readouts and graphs update as you experiment, and compare what you see with the key ideas below.
Things to try
- Use the buttons to force a convergent boundary and watch a mountain grow in the cross-section.
- Force a divergent boundary and watch new ocean crust stripes appear.
- Set a small relative velocity for a transform boundary and count the earthquakes.
- Compare the displacement graph for fast versus slow plates.
Key ideas you can learn
- Plates move at a few centimeters per year, driven by mantle convection.
- The relative velocity between two plates decides the boundary type: converging, diverging, or sliding past.
- Convergent boundaries build mountains and cause earthquakes; divergent boundaries create new crust; transform boundaries release stress as earthquakes without much vertical change.
- Displacement, mountain height and crust creation all accumulate over geological time.
Where this is used in the real world
This is the same reasoning used to explain the Himalaya (convergent), the Mid-Atlantic Ridge (divergent) and the San Andreas Fault (transform).
Who is this simulation for?
Students, teachers and curious learners of all ages.
For teachers: project it on the board, let students predict what will happen, then run it together. For students: change one thing at a time and write down what changes.
Frequently asked questions
How do scientists know plates actually move?
GPS measurements today directly track plate velocities of a few cm/year, matching the seafloor magnetic stripe patterns that recorded past spreading.
Why do convergent boundaries build the tallest mountains?
Sustained compression over millions of years thickens and uplifts crust faster than erosion can wear it down, as in the Himalaya.
Is the Continental Drift & Plate Motion Simulator free to use?
Yes. It is completely free, with no signup, no download and no ads inside the simulation. It runs in your web browser.
Does the Continental Drift & Plate Motion Simulator work on a phone or tablet?
Yes. It uses touch as well as the mouse, so you can drag objects with your finger. A larger screen makes the controls easier to see.
