Question 1 African superswell-Provides an example of a superswell and how certain aspects of the swell have been explained. In the third citation, it would be nice to know the background of how it is concluded that superswells are a 'recent' phenomenon. In the lithospheric heating section, it mentions Africa moving over certain hotspots, but doesn't indicate where these hotspots are, or their relative size. The two separate camps of mechanism of action are clearly delineated and easy compared. Since this page lacks any visuals, a heat map of the area underlying Africa compared to an area of no anomalous topology for the lithospheric heating section would illuminate the concept very well.

Dynamic topography-Possible driving mechanism for superswell formation. In the second paragraph, there is no mention of how material produced by mid-ocean ridges cools and condenses after being pushed away from the ridge, which causes its elevation relative to the ridge to sink. The article is very information dense, but doesn't go into much detail about what types of mantle material are susceptible to uplift. Also, since there aren't any visuals on this page, a picture of a geoid in a region of dynamic topography would be appealing. Large Low Shear Velocity Provinces-possible driving mechanism behind superswell creation. Separating headers for the two hypotheses of possible origin would be helpful. The seismological constraints section is very well written and informative, but the following section on possible hypotheses is not very in depth. The visuals on locations of LLSVPs are visually informative. I visual of the mechanism of plate upwelling would illustrate the possible mechanism section well.

Question 2 I propose to edit the already existing stub article on superswells, including mechanisms which create them, effects superswells have on the above topology, and locations at which they occur and unique components of those locations. These are valuable to a large audience because are areas that have very unique and interesting topology. For a specialist community, the driving mechanism behind them gives glimpses into the workings of the earth near the core-mantle boundary, most specifically the LLVSP's. The page will be structured into mechanisms of superswells, locations of currently active superswells, and superswell interaction with continental material. A possible illustration might include a heat map of the area underlying Africa as compared to a topological map, or a graph of mantle velocities underlying the plate compared to other plates.
