This online resource is an interactive simulation which traces the path of a rock from the time it is formed in a lava flow through the cycle of weathering, erosion, deposition and lithification.

All the processes are explained through a variety of interactive callouts using animations. This includes crystallisation and the partial melting which accompanies metamorphism.

Hyperlinks to photos also show a variety of landforms produced by a number of different erosional agents.

This interactive provides valuable visualisations which allow students to explore highly abstract concepts and apply their understanding to natural features of the landscape.
