The process that Sally is modeling in her diagram is the "Role of Volcanoes in the Earth's Systems". This particular system is called "the Cycle of Rock and Soil formation"
How do the individual parts of the model form the cycle?
The cycle of soil formation starts with the production of molten magma by the volcano.
The magma solidifies and cools, then they are transported, deposited and go through lithification.
After lithification, they become sedimentary rocks, and then through exposure to pressure, they become metamorphic rocks.
Over the years, as more and more layers are deposited onto the metamorphic rocks, pressure and heat build up creating molten magma.
The magma creates igneous rocks which after many years may be produced again as molten magma through an active volcano.
