Experiment: Click Return to original settings and select Limestone. Turn off Frost wedging and Other so that only Dissolving is selected. Using the Gizmo, test the effect of precipitation and temperature on the rate of dissolving.



Dissolved rock (low precip. )




Dissolved rock (high precip. )




Dissolved rock (low temp. )




Dissolved rock (high temp. )





Summarize your findings:






Dissolving occurs more quickly at low temperatures because cold water can dissolve more carbon dioxide than warm water. The greater the amount of dissolved carbon dioxide, the more acidic the water is and the faster the rate of dissolving.
