| − | 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).

| − | 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.
| + | In this comic, [[Randall]] equates Swimming pools with {{w|plate tectonics}}, to explain how deep ends form in said pools. Unfortunately, swimming pools aren't really formed by plate tectonics{{Citation needed}}. |

| − | {{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}}. | + | A {{w|swimming pool}} is a pool, typically used for swimming {{Citation needed}}. Most of these have a deep end and a shallow end. This is intentional, likely to accomadate for new swimmers to have somewhere to stand while accomadating for more confident swimmers for whom the floor would get in the way{{Actual citation needed}}. |

| − | 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. In this comic, the splash zone consists of natural geysers, fed by the bubbles of water that return upwards from the subducted plate.
| + | {{w|Subduction}} is a process in plate tectonics causes one plate to be pushed under another plate, causing the lower one to melt. This usually takes place between continental plates and oceanic plates, although it could happenwith two oceanic plates. The comic depicts the former; A oceanic plate subducting under a continental one. |

| − | 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.
| + | On the left image, there is the shallow end. The water is the shallow end is the shallowest in the pool, about the height of [[Megan]], excluding her head. Going right from there, the pool floor (Representing the oceanic plate) begins to curve downwards towards the subduction zone. As the floor goes down, the water gets deeper{{Citation needed}}. In the deepest area, it is labeled "Deep End" |
| | | | |
| − | Other comics that mention unusual tectonic plate motion include [[1388: Subduction License]] and [[1874: Geologic Faults]].
| + | |
| | + | At the bottom of the deep end, there is a curve and a deposit on the plate/pool floor. This is likely sediment buildup from waterborne debris that has settled there. |
