How does the temperature of lava affect how far the lava will flow?
The temperature of lava affects its viscosity, or how easily it flows. Hotter lava has lower viscosity and can flow more easily, often traveling further than cooler, more viscous lava. Cooler lava tends to be more sluggish and may not flow as far before solidifying.
This type of lava is thick stiff and does not flow easily.?
Aa
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 type of lava is thick stiff and does not flow easily?
Thick, stiff lava that does not flow easily is known as aa lava. Aa lava has a rough, blocky texture due to its high viscosity, making it difficult for the lava to flow smoothly. Aa lava typically moves in a jerky, slow manner and can form sharp, jagged edges as it solidifies.
What is the relationship with silica viscosity and lava flow?
An increase in the silica content of a lava increases it's viscosity. Viscosity can be thought of as a fluids resistance during deformation to shear or tensile stress, or in more simple terms, how easy or difficult it is to make a fluid flow. As viscosity increases, a fluid will flow less easily, so a lava with a high silica content will be more viscous and will flow less easily / more slowly than a low silica lava.
What type of eruption produces a gentle flow of lava?
A type of eruption that produces a gentle flow of lava is called an effusive eruption. In these eruptions, lava flows steadily and slowly, typically without explosive activity. The lava tends to have low viscosity, allowing it to flow easily across the surface of the volcano.
What is the density independent of lava flow?
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
Does temperature affect the speed of lava?
Yes, because the hotter lava gets, the easier it can flow. The reduced density of hot lava, plus reduced hardening of the leading edge, means that it will travel much more rapidly than cooler, thicker lava.
How does heat affect lava flow?
Heat effects the flow rate of lava because the hotter the lava is, the less viscous it is which allows it to flow faster than if it had a slow flow rate. If it has a low temperature, then the flow rate will be much slower because it has a high viscosity.
Is lava harmful?
Yes. Deaths from lava are fairly rare because lava usually flows slowly, but people have burned to death from it. Even when it doesn't kill, a lava flow can easily destroy people's homes.
Is there a difference between lava and lava flow?
Yes, there is a difference between lava and lava flow. Lava is the molten rock beneath the Earth's surface, while lava flow refers to the movement of lava as it travels down a volcano or hillside. Lava flow is the result of the eruption of molten rock, which can vary in speed and direction.
What forms when the lava ejected is too thick to flow?
When the lava ejected is too thick to flow, it solidifies near the vent and can form a dome-shaped feature called a lava dome. Lava domes are typically made of highly viscous lava, which does not flow easily. They can grow slowly over time as more lava is added to the dome from the eruption.
