pahoehoe is the more smooth lava flows.
a'a is the very jagged, sharp lava.
What else can I help you with?
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 the Kilauea have slow eruptions?
because pahoehoe is a slow erupting kind of lava as well as the fact that kilauea is a hawaiian volcano (that is the type)
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.
Is lava on a dome volcano shoot out lava or slow flow lava?
Lava on a dome volcano typically oozes out slowly due to its high viscosity and sticky nature. This slow flow allows domes to grow vertically and can occasionally lead to small rockfalls and collapses. The slow-moving lava poses less risk to surrounding areas compared to explosive eruptions seen in other types of 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 cool slow moving type of lava called?
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)
How is hawaiian lava different from composite cone lava?
Compared with the lava in composite volcanoes, hawaiian lava has a slow silica content, is runny, and erupts at a higher temperature.
How do you say lava in hawiian?
There are two types of lava in the Hawaiian language, the fast flowing lava is called pahoehoe, and slow flowing 'A'a
A lava flow with a surface of rough jagged blocks and sharp angular projections is called?
A lava flow with a surface of rough jagged blocks and sharp angular projections is called A'A lava flow. A'A lava is characterized by its slow-moving, clinkery texture formed by the cooling and breaking apart of the lava as it flows.

What type of lava is most dangerous?
the most dangerous type of lava is sticky lava because slow moving acid lava is more vicious
Why are lava flows rarely deadly?
Lava flows are usually slow moving, giving people time to escape.
