[[Cueball]] is once again getting his home inspected by [[Ponytail]], using the exact same device as in the first comic and also making the same introductory comment: &amp;quot;Oof. I was afraid of that.&amp;quot; This time, she alerts Cueball about {{w|water damage}}, normally caused by leaky pipes or roofs. Water damage is hazardous to homes due to its ability to instigate mold and have negative impacts on structural stability of the home. Instead of his home suffering from water damage, Ponytail claims that the crust under Cueball's home suffers from water damage. The Earth's crust typically {{w|groundwater|contains water}}; she could be referring to {{w|erosion}}, which is one cause of {{w|subsidence}} and even {{w|sinkhole}}s, a concern to homeowners, but it soon becomes clear that she has different effects in mind&lt;/ins&gt;.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

This leads to the formation of magma as the descending plate heats up. The subducted material includes water in the form of hydrated minerals as well as liquid water, originally from seawater and seabed sediments drawn into the subducting fault. This moisture is forced out of the medium it is transported in and [https://www.bgs.ac.uk/discovering-geology/earth-hazards/volcanoes/how-volcanoes-form-2/ acts to lower the melting point of the adjacent rock], relative to what it would otherwise be, allowing magma to form more easily above the subduction interface. The magma can then force its way to the surface to form volcanoes, as Ponytail alludes to. However, there is nothing that Cueball can actually do about this supposed problem.{{Citation needed}}&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
