Ground vs Air(地面対空気) Which is thicker--the ground or the air? (地面と空気、どっちが厚い?) Space (宇宙) Atmosphere (大気) Lithosphere (岩石圏) Asthenosphere (岩流圏) Based mostly on Conrad and Lithgow-Bertelloni (2006) DOI.1029/2005GL025621 (主にコンラッドとリスゴー・ベルテローニに基づいている(2006)DOI.1029/2005GL025621) Alt-text: Water is thinner than both, and fire is *definitely* thicker. (水は両方(地面と空気)よりも薄く、火は間違いなくより厚い。) xkcd: Ground vs Air ht
