these are two ways on how:
1. a water spray can cool down a larva flow,
2. and using really heavy stones (10-40 tones)

What kind of rock forms when volcanic rock cools?
The type of rock depends on how the volcano erupted and how quickly the lava cooled. Gaseous lava that is cooled is pumice, a stone so light it floats on water. Thick, slow moving lava hardens into rhyolite. Volcanoes in the Hawaiian islands sometimes have their lava cool quickly, forming a smooth, glassy black rock called obsidian. These are all classified as igneous rocks.
Why does lava take a long time to cool down?
Lava cools slowly because lava is a poor conductor of heat. Lava flows slow down and thicken as they harden.
What does crystal size indicate?
Crystal size in igneous rocks is generally a marker for how long magma or lava took to cool and solidify. Larger crystal size is indicative of slow cooling.
A slow moving body of ice?
A slow moving body of ice is a glacier.
What are the two types of magma and what makes them different?
I'm not sure... but the two different types of lava are: Viscous - sticky and slow moving, resulting in tall volcanoes Non Viscous - runny and fast moving, resulting in short and very spread out volcanoes (shield volcanoes)
Cool slow moving lava is called?
AA
What is cool and slow moving lava called?
Aa
What is slow moving cool lava called?
AA
What is the slow moving and hot moving lava called in Hawaiian?
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
Is lava on a dome volcano shoot out lava or slow flow lava?
It is very slow flowing lava, so slow you can't even see it moving. However this can change, as magma from below can produce a violent explosion.
What type of lava is most dangerous?
the most dangerous type of lava is sticky lava because slow moving acid lava is more vicious
Are cinder-cone volcanos viscous?
It is thick, slow moving lava called Pyroclastic Flow.also known as high viscosity
Why are lava flows rarely deadly?
Lava flows are usually slow moving, giving people time to escape.
What type of volcanoe is mauna loa?
It is a shield volcano. Rifts typically open in the seaward flanks, with lava fountains and slow-moving lava flows to the ocean.

Which lava is more viscous slow-moving lava or runny lava?
The difference in the flow of lava is determined by how viscous the magma of the volcano is. For Stratovolcanoes like those seen in the Cascades Range of the North Western United States, there magma is normally very sticky as it has a high concentration of Silica. The higher the concentration of silica within magma makes it stickier and will make it resist flow. This is why Stratovolcanoes often will erupt explosively, as there is no way for the gasses to simply passively leave during a lava flow. This viscosity traps the gasses and makes explosive eruptions much more likely as once the gasses finally are able to escape the level of gasses have built up to catastrophic levels within the volcano. On the other hand Hawaiian style volcanoes have a very low silica content within their magma chamber, and therefore have very flowable lava. This allows for the fire fountains and lava channels that are often times shown in magazines. These eruptions are often times passive in nature, as the gasses dissolved in the magma are easily able to escape during an eruption.
Why does cool water move slow?
Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.
