What Is The Viscosity Of Lava. The behavior of lava flows are mostly determined by the viscosity of the lava. Lava is the name for molten rock that has erupted onto the Earths surface - the red-hot material spilling from volcanoes.
Another way to stop a lava flow is to increase the lava flows viscosity Bryant 1991 and Scott 1989 by spraying it with water increasing the rate at which gas escapes from the flow stirring the flow or seeding the flow with foreign nuclei Bryant 1991. Lava is erupted during either nonexplosive activity or explosive lava fountains. If lava is forced to continue flowing after a certain critical relationship.
Viscosity definition is - the quality or state of being viscous.
Pahoehoe Flows - Basaltic lava flows with low viscosity start to cool when exposed to the low temperature of the atmosphere. This is because the lava has a hard time getting out and may burst out when it can. Between viscosity and rate of shear strain is achieved the lava changes to aa. Known by the Hawaiian names pahoehoe and aa or aa.
