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.
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.
Is pyroclastic material likely to form from low-viscosity lava?
No, pyroclastic material is not likely to form from low-viscosity lava. Low-viscosity lava typically flows easily and tends to produce effusive eruptions characterized by lava flows rather than explosive eruptions. Pyroclastic materials, such as ash and volcanic rocks, are more commonly associated with high-viscosity lava, which traps gas and leads to explosive volcanic activity.
What is lava called with high viscosity?
Lava with high viscosity is called slica-rich 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 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 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.
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.
Which type of lava would most likely form lava tube caves?
Pahoehoe lava, which has a smooth, rope-like texture and forms by flowing rapidly and cooling quickly, is more likely to form lava tube caves due to its ability to retain heat and flow for long distances before solidifying. Aa lava, with its jagged and blocky texture, tends to move more sluggishly and is less likely to create extensive tube structures.
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.
