A series of 3D cut out paper models that show the work of rivers including:

River delta model (deposition)

Grand Canyon model

Monterey Canyon model (offshore canyon)




All students need is a printer, scissors, and glue to make a 3-D model.


These models were developed by Tau Rho Alpha and myself as part of resources for Geoscience Australia and then The Geological Society fo America – both now giving them away for free.

Looking for more activities…see our Member Resources Page.
