Basically the way volcanoes errupt is determined by two factors
1) The amount of gas dissolved in the magma.
2) The viscosity of the magma - which is in turn determined by the temperature of the magma and how basic or acidic its composition is. Runny magmas are usually basic and thick magmas are usually acidic. The amount of magma (available to erupt) in the higher level magma chambers also has some effect on the eruption progress, as does the shape and stability of the volcano (e.g. with Mt St Helen's one side of the volcano collapsed, exposing the magma chamber).

∙ 11y agoif the shape of the volcano is like a shield the lava is runnier and less viscus but if the lava is more cone shape the lava is thicker and more viscus.this is shown because the shield volcano is much flatter meaning the lava moved quickly and spread round faster than the cone because it takes time to move down.

∙ 12y agoi dont think so. So the answer is probably no.......

∙ 12y agoIf it has indents on the left side of the mountain for example then it would got that way.

What is the shape of a volcano formed by fast-flowing lava?
Well it depends on how bad the lava flow is. If the lava is flowing slow then the shape of the volcano won't change much, But if it flows with force then bits of the volcano will fall off and change the shape of the volcano. Hope this answer helps!!
What flow from volcano?
lava
Does lava flow from a shield volcano?
Yes lava flows from a shield volcano.
How does a volcano gets its shape?
Lava. When the lava comes out of the volcano, gravity pulls the lava down the cone of the volcano, and depending the the viscocity of the lava, it forms a 'cone' or 'shield' as it cools. Thinner lava forms a shield volcano; thicker lava forms a steeper cone shape.
Who tall is AA volcano?
A'a is not a kind of volcano. A'a is a texture that a lava flow can take on, characterized by a surface covered in sharp fragments. There is no particular height to the lava flow, or height of volcano from which such a flow erupts.

What are lava flows on a volcano?
A lava flow is where lava flows down the side of a volcano.
What flow from volcano?
lava
Does lava flow from a shield volcano?
Yes lava flows from a shield volcano.
What volcano has pyroclastic flow in addition to liquid lava?
the volcano that has pyroclastic flow in addition to liquid lava is the composite or stratovolcano.

Does it spew lava or ash or flow?
A volcano will spew lava.
What happens when the lava reaches the top of the volcano?
Lava at the top of a volcano will generally flow downhill.

Is Mt Erebus an active volcano?
It is a lava flow, and has an AA (ah-ah) lava flow
What shape does sticky lava make?
The typical cone shape of a volcano happens when sticky lava erupts upward. Sticky lava creates a dome shape and the lava cools slowly.
