More viscous lava flows relatively faster explain?

Question: More viscous lava flows relatively faster explain?

The speed at which lava flows is influenced by several factors, including the temperature, viscosity, and gas content of the lava. Viscosity refers to a fluid's resistance to flow, and it plays a crucial role in determining how quickly lava flows.

More viscous lava flows relatively faster because it tends to form a thicker crust on its surface as it cools, which insulates the hotter, less viscous lava beneath. This insulation effect allows the less viscous lava to flow more quickly, as it is not impeded by the thicker crust.

On the other hand, less viscous lava flows more slowly because it does not form a thick crust and instead spreads out more thinly. As a result, the hotter, less viscous lava cools more quickly, which slows down the overall flow rate.

In summary, more viscous lava flows relatively faster than less viscous lava due to the insulating effect of the thicker crust that forms on its surface.
