Source sentences:
text: The viscosity of the lava fragments ejected by the blasts was, for basalt, relatively high.
text: Special conditions are needed for pahoehoe to form: lava with low viscosity (high temperature, low silica content), low effusion rate, and gentle slope.
text: Rapid flowing means lava loses heat quickly and its viscosity is pretty high.
text: The viscosity can be so high that the gas can only escape by blasting the magma from the vent.
text: If, on the other hand, the lava has a high viscosity (thick and pasty with a high gas and silica content) it is called Aa.
text: Since the viscosity is so high, the lava does not flow away from the vent, but instead piles up over the vent.
text: If the viscosity of the lava is high, a relatively low rate of shear strain may achieve the transition threshold, and the lava changes to a'a.
