What else can I help you with?
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.
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 lava or high-viscosity lava?

Is pyroclastic material likely to form from low-viscosity or high-viscosity lava?
low viscosity lava due to the violent eruption of the volcano
How does the viscosity affect of lava affect its flow rate?
Viscosity means how runny it is. Thus a lava with low viscosity will erupt fast and form long, wide spreading lava flows (eg Hawaii) and lavas of high viscosity will erupt slowly and form lava domes (eg Mt. St. Helens).
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.
Is phroclastic material likely to form from low - viscosity lava or high - viscosity lava?
Pyroclastic material is more likely to form from high-viscosity lava. This is because high-viscosity lava traps gases more effectively, leading to explosive eruptions that fragment the lava into ash, pumice, and other pyroclastic materials. In contrast, low-viscosity lava tends to flow more easily and is less explosive, resulting in less pyroclastic activity.
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.
What happens when the temperature-of lava increases?
When the temperature of lava increases, its viscosity will decrease. Viscosity is a measure of the magnitude of internal friction of a substance.
Is pyroclastic material likely to form from low viscosity lava or high viscosity lava Explain .?
Pyroclastic material is more likely to form from high viscosity lava. This is because high viscosity lava tends to trap gases more effectively, leading to explosive volcanic eruptions when the pressure is released. In contrast, low viscosity lava allows gases to escape more easily, resulting in gentler, non-explosive eruptions that produce primarily lava flows rather than pyroclastic material.
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.
