The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).

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.
Molten material that flows from volcanoes?
lava.
What is the name of how lava flows?
Lava flow
What is the difference between pyroclastic flows and lava flows?
Lava is molten rock at earth's surface. A pyroclastic flow is an avalanch-like flow of hot ash, rock, and gas that moves down a volcano's flanks at great speed.
What is Magma that flows onto Earth's surfaces called?
the answer is.....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
Molten material that flows from volcanoes?
lava.
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.

Lava flow

Lava is molten rock at earth's surface. A pyroclastic flow is an avalanch-like flow of hot ash, rock, and gas that moves down a volcano's flanks at great speed.
What can stop lava flows?
Lava flows can be stopped or deflected by ridges, valleys and depressions in the ground.
What happens when lava flows reach the sea?
When lava flows reach the sea, the lava rapidy cools to form an igneous rock.
Are lava flows harmful?
Yes. Lava flows can be extremely destructive. Since most lava flows move slowly, though, relatively few people have been killed by them.
