This annotated animation shows the potential increase in surface area which results from physical weathering. Students have the opportunity to calculate and compare surface area increases for two different scenarios: when a single mass weathers into cubical blocks versus plate-like blocks. Captions help students through calculations for determining the total surface areas of the different shapes.
