What else can I help you with?
How would you describe lava with a high viscosity?
Lava with high viscosity is thick and slow-moving, resembling thick honey or toothpaste. It tends to flow more sluggishly and can build up pressure, leading to explosive eruptions with volcanic ash and debris.
What is lava called with high viscosity?
Lava with high viscosity is called slica-rich lava
Does High viscosity lava flows faster than low viscosity lava?
No. Viscosity is a liquid's resistance to flow. So higher viscosity means a slower flow.
What is the viscosity of lava flow from a cinder cone volcano?
The viscosity of lava flow from a cinder cone volcano is typically high, leading to slower-moving lava flows. This is due to the higher silica content of the lava, which increases its viscosity. As a result, cinder cone volcanoes often produce short, thick flows that can cool and solidify quickly.
What kind of volcano erupts rhyolite?
Rhyolite is typically associated with explosive eruptions and is commonly erupted by stratovolcanoes or calderas due to its high silica content, viscosity, and gas content. These volcanoes are known for their explosive nature and can produce pyroclastic flows, ashfall, and lava domes.

How does the silica content of lava impact its viscosity?
Silica content is directly proportional to viscosity, so the higher the silica content of a lava, the higher its viscosity. high viscosity means a lava will be thick and slow moving, hence probably meaning an explosive eruption. lava's with a high viscosity include rhyolite and andesite whereas lava's with a low viscosity (runny ones) include basalt.

Is pyroclastic material likely to form from low-viscosity or high-viscosity lava?
low viscosity lava due to the violent eruption of the volcano
Is pyroclastic material likely to form from low-viscosity lava or high-viscosity lava?
you eat my butt
Does Krakatoa make pillow lava?
No. Pillow lava is basaltic, low-viscosity lava. Krakatoa is a stratovolcano with a style of ereuption more characteristic of high-viscosity andesitic lava.
What is ryolitic lava?
rhyolite is a type of lava
Rhyolite is associated with what type of eruption?
Rhyolite is associated with explosive eruptions.
Is rhyolite high in silica?
Yes, rhyolite is high in silica. It is a volcanic rock with silica content of around 70% or more. This high silica content contributes to its high viscosity and explosive nature during volcanic eruptions.
