it all depends on the silica content which makes high or low viscosity
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
Im not sure but I think its not fast but not slow so in the middle
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
No. Block lava is low-moving viscous lava, usually of andesitic or similar composition. A pyroclastic flow is a very fast-moving mixture of hot ash, rock and gas.
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
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.
Lava movement refers to the flow of molten rock on the Earth's surface, typically during a volcanic eruption. The movement of lava can vary in speed, from slow-moving oozing flows to fast-moving streams of molten rock. Lava flow direction is influenced by topography, gravity, and the viscosity of the lava.
Mount Etna's lava can flow at varying speeds depending on factors like viscosity and slope of the terrain. Typically, the lava flows at speeds ranging from a few meters per hour to several kilometers per hour. It can sometimes reach speeds of up to 60 kilometers per hour during fast-moving lava flows.
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.
Magma flows for a long period of time but named lava when out of the ground. It depends how fast the lava is travels, but you can usually run from it:)
No. Pahoehoe is lava that forms a smooth, ropey surface. It may flow relatively quickly at times, but often flows very slowly.
Fast flowing lava with low viscosity is called "pahoehoe." This type of lava has a smooth, rope-like texture and tends to move quickly across the surface due to its low viscosity, which allows it to flow easily. Pahoehoe lava often forms when basaltic magma emerges from a volcano.
