Rocks are generally deposited horizontally. After one rock layer has been deposited, another is laid down on top of it. Thus, the rocks on the bottom of the stack are the oldest, and the rocks on the top are the youngest. Once the rocks have been deposited they sometimes get moved around. They can...

This activity allows students to construct a small-scale model of liquefaction, a hazard associated with strong-magnitude earthquakes. The sand, water, and ping pong ball(s) represent the composites of soil: sediment, water, and air, respectively. The shaking, representative of seismic waves, will...

This activity allows students to experience what rocks and minerals go through during the rock cycle. The activity explains how to manipulate chocolate using heated water and a knife into different states representing metamorphic, igneous, and sedimentary rocks. Chocolate can be ground into small...
