Higher viscosity lava results in
WebA large amount of linked silica tetrahedra will result in magma or lava that is very viscous, meaning that it cannot flow easily (viscosity means resistance to flow). The temperature … Webviscosity (Murase and McBirney 1973; McBirney and Murase 1984; Spera 2001). However, commonly students expect the syrup with added solids to have a lower viscosity because it has a higher density; however, Jeffreys equation shows that viscosity is directly proportional to density, so an increase in density should produce an increase in viscosity!
