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.

Are Basaltic lavas generally hotter and more viscous than andesite lavas?
Basaltic lavas are generally hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which makes them flow more easily. Andesite lavas, on the other hand, have higher silica content, making them cooler and more viscous.
Are Basaltic lavas are generally hotter and more viscous than andesite lavas?
No, basaltic lavas are typically hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which results in their lower viscosity and ability to flow more easily. Andesite lavas, on the other hand, have higher silica content and are more viscous.
Is the composition of the hawaiian lavas felsic or mafic?
The composition of Hawaiian lavas is typically mafic, as they are rich in magnesium and iron and have a lower silica content. This composition gives them low viscosity and allows them to flow easily.
Are Sticky thicker lavas rich in silica?
Yes, sticky thicker lavas are rich in silica. This high silica content makes them more viscous and less likely to flow easily, leading to more explosive volcanic eruptions. Examples of these lavas include dacite and rhyolite.
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 is blood flow resistance?
The resistance of blood flow is what?
Are Sticky thicker lavas rich in silica?
Yes, sticky thicker lavas are rich in silica. This high silica content makes them more viscous and less likely to flow easily, leading to more explosive volcanic eruptions. Examples of these lavas include dacite and rhyolite.
Does resistance flow through a circuit?
No. Resistance does not flow. Resistance is the characteristic of a material that resists the movement of electrons and thus the flow of electrical current.
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.
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
A fluid resistance to flow is called?
A fluid's resistance to flow is called its viscosity.
Is it true that condensation is the resistance of a fluid to flow?
No, condensation refers to the process of a gas changing into a liquid state. The resistance of a fluid to flow is typically referred to as viscosity. Viscosity is a measure of a fluid's resistance to deformation or flow.
What is the resistance of a liquid's flow called?
The resistance of a liquid's flow is called viscosity. It is a measure of the fluid's resistance to deform or flow. Materials with high viscosity flow more slowly, while those with low viscosity flow more easily.
Fluid basaltic lavas commonly form?
Fluid basaltic lavas commonly form from low-viscosity magma with high temperatures and low silica content. When erupted, these lavas tend to flow long distances and form thin, low-angle lava flows that can extend for many kilometers before solidifying. Basaltic lavas are common at hot spot volcanoes, mid-ocean ridges, and shield volcanoes.
