Did Krakatoa have high viscosity lava? - Answers
2024年6月5日 · No, Krakatoa is known for its explosive eruptions due to its low-viscosity lava. This type of magma allows gas bubbles to rise quickly to the surface, resulting in powerful and destructive eruptions.
What factors control the viscosity of magma and lava?
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.
How would you describe lava with a high viscosity? - Answers
2024年6月13日 · 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 ...
Which lava is more viscous slow-moving lava or runny lava
2024年5月26日 · The difference in the flow of lava is determined by how viscous the magma of the volcano is. For Stratovolcanoes like those seen in the Cascades Range of the North Western United States, there ...
Do composite volcanoes have viscous lava? - Answers
2024年6月11日 · The high viscosity of the lava contributes to the steep-sided nature of composite volcanoes and can lead to explosive eruptions. This answer is: 👍 Helpful ( 0 ) 👎 Not Helpful ( 0 )
What is the behavior of lava with silica content being high
2024年5月26日 · Lava with high silica content tends to be more viscous and flow more slowly, leading to explosive eruptions. In contrast, lava with low silica content is less viscous and flows more easily ...
How does the viscosity affect of lava affect its flow rate?
2024年6月30日 · 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 ...
What is a substance that has a high viscosity? - Answers
2024年6月13日 · 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.
Does toothpaste have high viscosity? - Answers
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 ...
Is felsic lava thick and sticky? - Answers
2024年6月25日 · Yes, felsic lava is thick and sticky due to its high silica content, which increases its viscosity. This can cause felsic lava to flow slower and have a tendency to create explosive eruptions due ...
