Pools, like oceans, contain water.{{Citation needed}} This comic produces a schematic for the former, derived from science about the latter. On Earth, the surface consists of tectonic plates which move around. In this comic, [[Randall]] equates swimming pools with {{w|plate tectonics}}, to explain how deep ends form in said pools. In actuality, swimming pools aren't formed by plate tectonics (at least, not the ones made by people; we can't be sure about the others). | Pools, like oceans, contain water.{{Citation needed}} This comic produces a schematic for the former, derived from science about the latter.

This is intentional, usually to accommodate less confident swimmers to have somewhere to stand up when needed, while also allowing for activities (such as diving, underwater swimming, rescue practice, etc.) which would not be possible in shallower water. |
{{w|Subduction}}, a geological process in which one plate slips beneath another and is forced down into the mantle, is shown here as the reason swimming pools have deep ends. This usually takes place between continental plates and oceanic plates, although it could happen with two oceanic plates. The comic depicts the former, an oceanic plate subducting under a continental one. With tectonic plates, this often results in a deep {{w|oceanic trench}} where one plate slides beneath the other, as well as a {{W|volcanic arc|chain of volcanoes}} above areas farther along the subducting plate, where rock that has liquefied from the subduction comes toward the surface as magma and erupts in volcanoes. An example is the {{w|Cascadia Subduction Zone}} in which the {{w|Juan de Fuca Plate}} is subducting beneath the {{w|North American Plate}}, creating the volcanic {{w|Cascade Range}}. | {{w|Subduction}}, a geological process in which one plate slips beneath another and is forced down into the mantle, is shown here as the reason swimming pools have deep ends.
