What is fast flowing lava with low viscosity called?
Fast flowing lava with low viscosity is called "pahoehoe." This type of lava has a smooth, rope-like texture and tends to move quickly across the surface due to its low viscosity, which allows it to flow easily. Pahoehoe lava often forms when basaltic magma emerges from a volcano.
Lava that is cooler and slower-moving is called?
Lava that is cooler and slower-moving is called "pahoehoe." Pahoehoe lava has a smooth, rope-like or wrinkled surface texture due to its lower viscosity, which allows it to flow more easily compared to aa lava.
Hot fast moving lava?
Hot, fast-moving lava is typically associated with Hawaiian-style eruptions, which feature low viscosity lava that can flow rapidly down slopes. This type of lava is usually characterized by its high temperature and ability to travel great distances in a short amount of time, posing a significant hazard to surrounding areas. It's crucial for residents near active volcanoes to stay informed about lava flow risks and heed evacuation orders to ensure their safety.
What is cool slow moving type of lava called?
these are two ways on how: 1. a water spray can cool down a larva flow, 2. and using really heavy stones (10-40 tones)
What is the relationship between the viscosity of andesitic lava and its flow behavior during volcanic eruptions?
The viscosity of andesitic lava affects its flow behavior during volcanic eruptions. Higher viscosity lava flows more slowly and tends to form thicker, blockier lava flows, while lower viscosity lava flows more easily and can travel further before solidifying. This relationship influences the type and intensity of volcanic eruptions.
What is lava called with high viscosity?
Lava with high viscosity is called slica-rich lava
What is fast flowing lava with low viscosity called?
Fast flowing lava with low viscosity is called "pahoehoe." This type of lava has a smooth, rope-like texture and tends to move quickly across the surface due to its low viscosity, which allows it to flow easily. Pahoehoe lava often forms when basaltic magma emerges from a volcano.
What is called hot fast-moving lava is called?
mafic
What is the slow moving and hot moving lava called in Hawaiian?
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
Lava that is cooler and slower-moving is called?
Lava that is cooler and slower-moving is called "pahoehoe." Pahoehoe lava has a smooth, rope-like or wrinkled surface texture due to its lower viscosity, which allows it to flow more easily compared to aa lava.
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.
What is lava movement?
Lava movement refers to the flow of molten rock on the Earth's surface, typically during a volcanic eruption. The movement of lava can vary in speed, from slow-moving oozing flows to fast-moving streams of molten rock. Lava flow direction is influenced by topography, gravity, and the viscosity of the lava.
Are cinder-cone volcanos viscous?
It is thick, slow moving lava called Pyroclastic Flow.also known as high viscosity
What are the differences between pahoehoe and Aa what kind of eruption produces these types of lava-?
Pahoehoe is hot, fast-moving lava that has a low viscosity. AA lava has a cooler temperature and moves more slowly. Quiet eruptions are the type that produce these two types of lava.
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).
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.
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.
