Abstract          How abundant are different types of rocks under certain conditions and how will changing these conditions alter the abundance of the different types of rocks? My project hopes to provide information on the rock cycle that could be used in the future to help describe the rock cycle on mars.
         I attempted to solve my problem by using a STELLA equation, which I converted into a JavaScript model. By experimenting with the initial conditions in the JavaScript model, I decided that the smallest change to these initial conditions would affect the entire cycle. Based on my original initial conditions (which are listed in the paper), igneous rocks were the most abundant, followed by metamorphic rock then sedimentary rock. When I changed the original initial conditions, this order of abundance remained the same; however, the degree to which one type of rock was more abundant than another type of rock changed. The ratio of the amount of a certain type of rock to the materials from which that type of rock was formed also changed.
