Hi, Kamron– >> The entire crust is floating on a series of alternating levels of solid and liquid layers. Seismic shear-waves (S-waves) cannot travel through liquid, yet they travel through all of the Earth's crust and mantle – they are stopped by the core, telling us that the outer core is liquid. They do not show us your layers. >> All the canyons were large cracks that opened up in the crust and the rivers just follow the natural lowest points Shortly after you last claimed that about the Grand Canyon, I had a really good look at it from an airliner window. You have clearly never looked that way at the Colorado river just downstream of the G.C.; the canyon follows in loving detail the meandering pattern we see in any shallow-grade river section. The loops constantly miss intersecting each other by a tiny bit, leaving a thin bit of plateau between them – and a much larger bit of plateau inside each loop, connected only by the thin "isthmus" between loops to the main plateau. The edges of the canyon parallel the river through every curve, maintaining a constant width (if measured perpendicular to the river at every point). There is _no way_ this could have been pulled apart in this pattern. –Doug
