A {{w|swimming pool}} is a pool of water, typically used for swimming. Most of these have a deep end and a shallow end. This is intentional, usually to allow less confident swimmers to have somewhere to stand up when needed, while also accommodating activities (such as diving, underwater swimming, rescue practice, etc.) which would not be possible in shallower water. | A {{w|swimming pool}} is a pool of water, typically used for swimming.

| β | {{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 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}}. |
| β | A splash zone is an area of a waterpark with water being sprayed around, allowing people to get wet without the need to get into the pool. It is not a geological term, but {{W|supralittoral zone|splash zone}} can mean the area next to a coastline that gets splashed by waves.

It is not a geological term, but {{W|supralittoral zone|splash zone}} can mean the area next to a coastline that gets splashed by waves. In this comic, the splash zone is actually geysers, fed by the bubbles of water from the subduction. While this particular scenario as shown in the comic is obviously far-fetched, subduction zones do create similar effects: water moving up from subducting plates is the origin of many {{W|volcanic arc|volcanic arcs}}. These volcanic systems sometimes include features such as the geysers depicted in the comic's splash zone. |
The title text refers to {{W|back-arc basin|back-arc basins}}, zones of depression that sometimes occur slightly beyond volcanic arcs due to a rift in the tectonic plate. The ban on running in this area likely has more to do with its proximity to the pool area than any danger intrinsic to back-arc basins. A typical safety rule around swimming pools is to avoid running on the pool deck to prevent injuries due to slipping and falling on the hard deck. | The title text refers to {{W|back-arc basin|back-arc basins}}, zones of depression that sometimes occur slightly beyond volcanic arcs due to a rift in the tectonic plate.
