Very fluid lavas have low viscosity. Lavas decrease in viscosity with lessening amounts of silicon. Mafic lavas are lower in silicon and therefore more fluid in nature.

What causes lava to be runny and fluid?
Silica content of lava, as well as the temperature of the lava.
Does hot spot have lava viscous or fluid?
no
Very fluid balsaltic lava may erupt out of fissures in the surface When the lava hardens it may form a feature called a?
Lava plateau
Is composite volcano lava viscous or fluid?
viscous
What volcanoes form extensive fluid lava flow that erupts numerous times?
Shield volcanoes form extensive fluid lava flow that erupts numerous times.
What kind of lava does Haleakala have?
it has aa lava, so it is not fluid like, but still basaltic.
What causes lava to be runny and fluid?
Silica content of lava, as well as the temperature of the lava.
Lava plateaus forms when?
Lava plateaus form when fluid basaltic lava flows out of fissures.
What is the fluid or semi-fluid material from which ingneous rock is formed?
lava
Fluid rock material from a volcano?
lava
Does hot spot have lava viscous or fluid?
no
Very fluid balsaltic lava may erupt out of fissures in the surface When the lava hardens it may form a feature called a?
Lava plateau
What is fluid rock?
lava= material flowing from a volcano
Is composite volcano lava viscous or fluid?
viscous
What volcanoes form extensive fluid lava flow that erupts numerous times?
Shield volcanoes form extensive fluid lava flow that erupts numerous times.
What type of magma are lava plateaus made from?
Lava plateaus are formed by highly fluid, basaltic lavas.
Is basaltic lava less fluid than andesitic lava?
No. Basaltic lava has less silica than andesitic lava which makes it less viscous and so basaltic lava flows more easily than andesitic lava.
