What is the importance of a silica and oxygen in lava flow speed?
Silica and oxygen content in lava affects its viscosity, which in turn impacts flow speed. Lava with higher silica content tends to be more viscous and flows slower, while lava with lower silica content flows faster. The presence of oxygen also influences lava's ability to flow by affecting its gas content and pressure.
What are the streams of molten lava spilled out of a volcano called?
Streams of molten lava out of a volcano are called 'lava flows'.
What was the speed of lava flow from mount vesuives on 79ad?
The 79 AD eruption of Mount Vesuvius did not produce lava flows. It was a Plinian eruption, produducing a massive ash plume and pyroclastic flows. Pyroclastic flows are not lava flows, they are masses of hot ash, rock, and gas that resemble avalanches. Nobody was able to clock the speed of these flows, but by comparing it to similar events it is likely that these flows moved at well over 100 mph.
What is Magma that flows onto Earth's surfaces called?
Magma that flows onto Earth's surface is called lava.
What is lava movement?
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.

Does all lava flow at the same speed?
No. The fastest lava flows on earth have been recorded at Mount Nyiragongo in the Congo flowing at 60 mph (100 km/h). In most cases, however, lava flows very slowly. Blocky lava flows are the slowest, moving at speeds comparable to glaciers.

What are lava flows on a volcano?
A lava flow is where lava flows down the side of a volcano.
Opening where the lava flows?
the opening where the lava flows is call a vent
What is the relationship between the viscosity of andesitic lava and its flow behavior during volcanic eruptions?
The viscosity of andesitic lava affects its flow behavior during volcanic eruptions. Higher viscosity lava flows more slowly and tends to form thicker, blockier lava flows, while lower viscosity lava flows more easily and can travel further before solidifying. This relationship influences the type and intensity of volcanic eruptions.
What is Magma that flows onto Earth's surfaces called?
Magma that flows onto Earth's surface is called lava.

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.
What flow from volcano?
During a volcanic eruption, lava flows from the vent of the volcano, following paths of least resistance down the slopes. The speed and distance of the lava flow depend on various factors such as the type of lava, gradient of the slope, and presence of obstacles. Lava flows can cause destruction to surrounding areas and communities in the path of the flow.
Are all lava flows the same?
No. Lava flows vary in composition. Most lava flows consist of basaltic lava, which can flow as smooth phoehoe or form jagged and broken a'a. Other lava flows are more viscous and will have blocky surfaces and tend to be short and thick.
When and why did lava flows?
Lava flows occur when molten rock, or magma, erupts from a volcano onto the Earth's surface. This usually happens during volcanic eruptions, when pressure builds up beneath the Earth's crust and forces magma to the surface. Lava flows can vary in size and speed, depending on the viscosity and gas content of the magma.
