CORRECTION: This infographic was updated on July 27, 2018, to correct the relative viscosities of pahoehoe and aa lava flows. Pahoehoe lava flows do not have higher viscosity than aa lava flows. They have lower viscosity.

The Pahoehoe mafic lava has lower viscosity, so it flows quickly and the AA mafic lava has higher viscosity, so it flows slower, is it right? I think it's mistaken on the graphic.
I love these articles, they teach a lot about daily chemistry...
Regards.
