Higher viscosity (felsic) lava is typically less hot than the lower viscosity (mafic) lava. Felsic magmas can erupt at temperatures as low as 650 to 750 °C. Poorer in aluminum and silica than felsic lavas, and also commonly hotter, intermediate lava (in the range of 750 to 950 °C), tends to be less viscous. Mafic to ultramafic lavas are believed to erupt up to 1600°C in the past.
What else can I help you with?
Does High viscosity lava flows faster than low viscosity lava?
No. Viscosity is a liquid's resistance to flow. So higher viscosity means a slower flow.
Is pahoehoe fast or slow?
Pahoehoe is hotter than other lavas. It is basaltic lava, which is hotter than the other compositional varieties found on earth today. It is also generally hotter than a'a, another common variety of basaltic lava.
How thick is the lava from a cinder volcano?
The thickness of lava is generally dependent on the eruption rate of the volcano. The flow rate of lava is measured by the lava's viscosity. Highly viscous lava does not flow well or travel great distances. Low viscosity lava can flow for great distances.
Are hawaiian volcanoes low or high in viscosity?
Hawaiian volcanoes are typically low in viscosity, meaning they have a relatively fluid lava composition compared to other types of volcanoes. This low viscosity allows the lava to flow more easily, resulting in gentle eruptions characterized by flowing lava streams rather than explosive eruptions.
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.
Does High viscosity lava flows faster than low viscosity lava?
No. Viscosity is a liquid's resistance to flow. So higher viscosity means a slower flow.
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.
Is pahoehoe fast or slow?
Pahoehoe is hotter than other lavas. It is basaltic lava, which is hotter than the other compositional varieties found on earth today. It is also generally hotter than a'a, another common variety of basaltic lava.
Is the sun hotter than molton lava?
Yes. The sun is much hotter and even the hottest lava.

What is the difference between lava and water?
Lava is molten rock that comes from the Earth's mantle, whereas water is a liquid compound made of hydrogen and oxygen. Lava is much hotter than water, reaching temperatures of over 1,300 degrees Fahrenheit, while water boils at 212 degrees Fahrenheit. Additionally, lava is denser than water and flows more slowly due to its high viscosity.
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.
What is the diffference between magna and lava?
the diffenence is tht manga is hotter than lava
Why is orange the fast flowing flow volcano?
The orand lavayou see is basaltic lava. One important aspect of a liquid is a property called viscosity, or the resistance to flow. For example, maple syrup has a higher viscosity than water. Compared to other types of lava, basaltic lava does not have a lot of silica in it. The low silica content makes the lava less viscous. Basalt also has a migher melting point than other types of rock, so the lava is hotter, so hot that it glows orange or red. The higher temperature also lowers viscosity, as it does for nearly all liquids.

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.
Between mafic lava and felsic lava which flowsfaster?
Mafic lava is hotter than felsic lava and therefore flows faster.
