Mantle Viscosity and Genesis Flood Models
When people need to get the oil changed in a vehicle, the word viscosity is likely to be used. To oversimplify, viscosity refers to thickness. Drop a pebble in a glass of water and it sinks quickly. Do the same in a glass of high-viscosity motor oil, it is much slower. Maybe a geologist slices into a pie and thinks about cutting through the lithosphere and into the magma, but I digest — I mean, digress. Sort of. That liquid rock down below also has viscosity. This affects the thinner areas of the lithosphere. Earth crust cutaway illustration derivative, Wikimedia Commons / Washiucho (Public Domain) Uniformitarian geologists believe this thinning (deformation) is extremely slow, and creation scientists believe it to be much quicker. Secular geologists believe that glacial rebound affects viscosity in certain areas, but it has been shown to be similar in non-glacial areas as well. Creationists use Genesis Flood and the subsequent Ice Age in their models and find that rebound is much mo
