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.
yes. lava can have high viscosity and also low viscosity. most of the time the viscosity level is high

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, low viscosity lava flows faster than high viscosity lava. Low viscosity lava is more fluid and can move more easily, while high viscosity lava is more sticky and tends to move more slowly.
Is pyroclastic material likely to form from low-viscosity lava or high-viscosity lava?

How does the viscosity affect of lava affect its flow rate?
Viscosity is a measure of a fluid's resistance to flow. Higher viscosity lava flows more slowly because it is more resistant to deformation and requires more force to move. Lower viscosity lava flows more quickly as it can deform and flow more easily.
What is lava's resistance to flow?
The resistance to flow of lava depends on its viscosity, which is influenced by factors such as temperature, composition, and gas content. Lava with low viscosity (more fluid) flows more easily, while lava with high viscosity (more sticky) flows less easily. The resistance to flow can also be affected by topography and the presence of obstacles in the lava's path.

No, low viscosity lava flows faster than high viscosity lava. Low viscosity lava is more fluid and can move more easily, while high viscosity lava is more sticky and tends to move more slowly.
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

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.
Would the typemagma mean the Eyjafjallajokull Volcano has high medium or low in viscosity?
Eyjafjallajokull Volcano has medium viscosity. The term "magma" is used to describe molten rock below the Earth's surface, while "lava" is used for molten rock that has reached the surface. Eyjafjallajokull's eruption in 2010 produced lava flows of medium viscosity.
How does the viscosity affect of lava affect its flow rate?
Viscosity is a measure of a fluid's resistance to flow. Higher viscosity lava flows more slowly because it is more resistant to deformation and requires more force to move. Lower viscosity lava flows more quickly as it can deform and flow more easily.

The resistance to flow can also be affected by topography and the presence of obstacles in the lava's path.
What kind of viscosity lava does Mount Tambora have?
Mount Tambora typically produces highly viscous lava due to its high silica content. This results in the lava being thick and slow-moving, leading to more explosive eruptions.
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 is the measure of lavas mobility called?
The measure of a lava's mobility is called viscosity, which refers to the resistance of a substance to flow. Lava with low viscosity is more fluid and flows more easily, while lava with high viscosity is thicker and flows more slowly.
