What two factors that influence the viscosity of lava flow?
Minerology of the area
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.
Does High viscosity lava flows faster than low viscosity lava?
No, low viscosity lava flows faster than high viscosity lava. Low viscosity lava is more fluid and can move more easily, while high viscosity lava is more sticky and tends to move more slowly.
How does the viscosity affect of lava affect its flow rate?
Viscosity is a measure of a fluid's resistance to flow. Higher viscosity lava flows more slowly because it is more resistant to deformation and requires more force to move. Lower viscosity lava flows more quickly as it can deform and flow more easily.
What affects the speed of lava flows?
The speed of lava flows is influenced by several factors including the viscosity of the lava (more viscous lava flows slower), the slope of the terrain (steeper slopes can result in faster flows), and the volume of lava erupting (larger volumes can flow more rapidly). Additionally, external factors such as the presence of obstacles or changes in topography can also affect the speed of lava flows.
