Viscous lava contains a high amount of silica, which increases its thickness and resistance to flow. This type of lava often includes gas bubbles, which can contribute to explosive volcanic activity when pressure builds up. Additionally, it may contain various minerals and crystals, depending on the specific composition of the magma from which it originates. Overall, the high viscosity of this lava type leads to more dramatic eruptions compared to less viscous, fluid lava.
What else can I help you with?
Which lava is less viscous rhyolitic or basaltic?
Basaltic lava is less viscous.
Does rhyolite lava have high viscosity?
Yes. Rhyolitic lava is extremely viscous, thousands to hundreds of thousands times more viscous that basaltic lava.
What are the characteristics of viscous lava flows?
Viscous lava flows are typically thicker and move more slowly than less viscous lava flows. They have a higher silica content, which makes them more resistant to flow. Viscous lava flows tend to form steep-sided volcanoes and are associated with explosive eruptions.
Difference between viscous and non viscous lava?
Viscous lava is very sticky and thick and is more felsic (ie it contains more silica) than non-viscous lava. This type of lava makes for a very explosive volcano, because it's so sticky that it sticks to itself and can't exit the volcano until it explodes violently. Non-viscous lava is more runny and is more mafic (has more iron, less silica). Volcanoes with non-viscous lava are less explosive because the lava just runs out slowly and no pressure builds. The Hawaiian islands are formed from volcanoes with non-viscous lava.
What are the difference between acid lava and basic lava?
Acid lava comes from composite cones,is slowly moving and viscous while basic lava comes from shield volcanoes,is non viscous, runny and flows faster
Which lava is less viscous rhyolitic or basaltic?
Basaltic lava is less viscous.
Which one hardens faster runny or thick lava?
Thick, highly viscous lava.
Does rhyolite lava have high viscosity?
Yes. Rhyolitic lava is extremely viscous, thousands to hundreds of thousands times more viscous that basaltic lava.
Is yellowstone's lava runny?
No. The lava there would be very viscous.

Is lava thin and flows easy?
Lava is melted rock, it is quite viscous.
What are the difference between acid lava and basic lava?
Acid lava comes from composite cones,is slowly moving and viscous while basic lava comes from shield volcanoes,is non viscous, runny and flows faster
What is a volcanic dome?
I don't know about viscous, but a lava dome is a steep-sided dome of thick lava extruding from a volcanic vent.a viscous lava dome is when the lava from the volcano contains alot of silica. Viscous=sticky. So the lava cools quickly of the sides of the volcano. And often a viscous lava dome volcano is explosive.
Why is a lava dome called a lava dome?
A lava domes is a structure that forms when a volcano extrudes very viscous lava that builds into a dome-shaped pile rather than flow downhill.
What is the composition of a lava dome?
Lava domes are generally composed of felsic, highly viscous lava, usually dacite or rhyolite.
Which is more viscous honey tar water or lava?
From thickest to thinnest: lava, tar, honey, then water.
