Wow; it took longer than I care to admit to realize 'thick' wasn't 'viscosity'...but 'altitude'. (i.e., height/thickness re: Kynde's comment) Elvenivle (talk) 01:08, 17 December 2019 (UTC)

Not altitude, but height or thickness... --Kynde (talk) 11:03, 17 December 2019 (UTC)
^ Yes, that. Correction added; I meekly blame word choice on keyboard dead zones. Elvenivle (talk) 20:22, 17 December 2019 (UTC)

It's probably worth mentioning in the explanation which map projection Randall chose to use for this comic from those listed in a previous comic about map projections. Ianrbibtitlht (talk) 02:22, 17 December 2019 (UTC)

And by these metrics, blood is even thinner than water... Template:unsignedip

I assume ocean ridges have a very thin crust, meaning they get the ratio more towards air? I am not at all a geologist, so I ask this question, because ridges would intiutively appear to have a bigger crust, as they stand out from the ground. "That definition would, of course, have resulted in a significantly different picture where the air is thicker than the ground only inside small areas around mid-ocean ridges" should be explained by someone who knows why it is the case. --Lupo (talk) 14:26, 17 December 2019 (UTC)

Mid-ocean ridges are raised above the ocean surface--Iceland is actually the high point on one of them. In other places they're trenches, though. Since seafloor crust is spreading at those points, it's at its thinnest there on average. Nitpicking (talk) 02:08, 18 December 2019 (UTC)
