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.

∙ 14y agoViscous lava is lava that is thick. For example a cinder cone or composite cone's lava is viscous. Because it cools faster than it moves, a composite cone has steeper flanks. On the other hand a shield volcano's lava is very low in silica, making it less viscous. Therefore A this lava flows off the flanks and makes this volcano a dome shape because the lava is able to spread to all parts of the volcano.

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 viscosious?
In candle making viscosity pertains to the thickness/heaviness of wax. An example is the difference between pure paraffin wax vs. beeswax. The same wick will not work in the same size candle jar. Paraffin burns almost twice as fast as beeswax. It's thinner & lighter so it carries up the wick smoothly. It takes a wick generally 3 sizes larger to burn the same candle made with beeswax. Kind of like the difference between olive oil & motor oil. I hope this helps.Regards,~ pat ~
What is a non viscous flow?
Viscosity denotes opposition to flow.
Difference between homogeneous and non homogeneous materials?
Non-homogeneous materials have two or more phases.
What is the difference between non spontaneously and spontaneously?
spontaneously are natural impulses
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 the difference between viscous and non viscous fluid flow?
it mean that it can not be compressed
Which one hardens faster runny or thick lava?
Thick, highly viscous lava.
What does the word non viscous mean?
Non-viscous is a scientific term that refers to the pouring characteristic of a liquid. A non-viscous liquid is one that pours thinly, with minimal bulging, drop formation or trailing string formation. An example of a non-viscous liquid would be alcohol; a viscous liquid (the opposite) would be maple syrup.
What is name of landform created by repeated flows of lava?
A trap basalt (or flood basalt) is a landform created by a large eruption or repeated eruptions of flowing non-viscous basalt lava, sometimes covering huge areas of land or seafloor.
What are the two types of magma and what makes them different?
I'm not sure... but the two different types of lava are: Viscous - sticky and slow moving, resulting in tall volcanoes Non Viscous - runny and fast moving, resulting in short and very spread out volcanoes (shield volcanoes)
What is the difference between a proposition and a non proposition?
difference between a proposition and non proposition
What is the difference between agriculture and non-agriculture?
Agriculture is farming and non-agriculture is non farming.
Difference between typing and non typing keys?
Difference between typing and non typing keys
What is difference between Cognizable and non-cognizable offences?
Cognizable offences are serious crimes in which police can make an arrest without a warrant, while non-cognizable offences are less serious crimes in which police cannot make an arrest without a warrant and need permission from the court. Cognizable offences generally have higher penalties and are investigated more thoroughly compared to non-cognizable offences.
Is blood Viscous or non viscous?
Blood is viscous, as it contains a hugely populous density of red blood cells therefore making it viscous. A comparison would be to water, which is less than 3 times as viscous as blood, as it contains around less than 3 times the amount of molecules than in blood.
