Well lava is melted rock, so it's not as loose as say, water.
There is fast lava though too. How slow it is depends on it's pH.
it depends on how steep the slope is.
Mauna Loa does not have slow gentle flowing lava
Mauna Loa does not have slow gentle flowing 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.
Mauna Loa does not have slow gentle flowing lava
some acids can slow it down,, thick substances CORN STARCH is a good one Lava is Lava you make no sense
the most dangerous type of lava is sticky lava because slow moving acid lava is more vicious

Compared with the lava in composite volcanoes, hawaiian lava has a slow silica content, is runny, and erupts at a higher temperature.
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.
