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).

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!!
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 can errupt to to bring lava flow to earts surface?
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.
Which village was threatened by the 1983 lava flow?
The village threatened by the 1983 lava flow in Hawaii was Kalapana. It was eventually destroyed by the lava flow from the Kilauea Volcano.

What are lava flows on a volcano?
A lava flow is where lava flows down the side of a 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.
What happens when the lava reaches the top of the volcano?
Lava at the top of a volcano will generally flow downhill.

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.

The explosiveness and shape of a volcano is determined by?
The amount of lava and the thickness of the hole in which the lava rises up. Also the steepness of the actual volcano

What flow from volcano?
During a volcanic eruption, lava flows from the vent of the volcano, following paths of least resistance down the slopes. The speed and distance of the lava flow depend on various factors such as the type of lava, gradient of the slope, and presence of obstacles. Lava flows can cause destruction to surrounding areas and communities in the path of the flow.
