-Combining several of these features and changing the `coordinate system` to `spherical` can create the model setup shown in Figure 2: A plate subducting beneath an oceanic plate and a rising plume impinging on the base of the lithosphere between a mid-ocean ridge and a passive margin. The resulting input file is just 85 lines of GWB input formatted in the same style as in the example input file above.
+A more complicated example (only requiring 85 lines) features a spherical geometry, a spatially variable subducting plate, continental plate, oceanic plate and plume can be seen in Fig 2.
 
 ![A schematic example of what can be built with 85 lines of a GWB input file formatted in the same way as in the example input file shown above. This includes a slab with variable dip and thickness along strike and down dip, subducting under an oceanic plate on the right side of the ridge, as well as a passive continental margin with layers of variable on the left side of the ridge, and a mantle plume beneath the ridge. The temperature of the continent is linear, the oceanic plates are defined by a half-space cooling model, the slab temperature is defined by a mass conserving temperature model and the plume adds heat based on a Gaussian around the center.\label{fig:example}](../../sphinx/_static/images/user_manual/basic_starter_tutorial/BST_19.png)
