These activities are longer and can take up to a whole class period to conduct.

• Carbon Dioxide Exercise Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years.
• Describe and Interpret Images: Folded Strata A think-pair-share activity which has students describe and interpret an image of a classic recumbent fold overlying a thrust fault.
• Mapping Plate Boundaries Students can discover plate boundaries by plotting different sets of earthquakes and volcanic eruptions on maps. These are then stacked on the overhead projector, outlining the tectonic plates.
