What else can I help you with?
What are the two factors control the explosiveness of a volcano?
The viscosity of the magma and its gas content.
What shape is a dome volcano?
the shape of a dome volcano is like an triangle
How does the type of material that erupts from a volcano determine the shape of the volcano?
The shape tells a geologist how viscous (thick and sticky) the lava was. A taller volcano, such as a cone, was formed by thicker lava; a low volcano, such as a shield volcano, was formed by very runny lava.
What shape of volcano is shield volcano?
A shield volcano is low and wide.
What is the shape of a volcano with low silica?
Shield Volcano
What does magma composition play a major role in?
The type of rock formed when the magma cools. The type of volcano or volcanic intrusion that is formed The explosiveness of volcanic eruptions.
How explosively or quietly a volcano erupts is not affected by?
If a volcano erupts more explosively, the lava spewing out tends to reach farther, possibly ruining a near by town. If it erupts more quietly, not as much lava tends to spew out. However, any eruption will cause harm to the atmosphere because it releases harmful pollutants.
What type of cone or shape does the Kilauea's volcano have?
Kilauea is a shield volcano.
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 determines a fluids shape?
A fluids shape is determined by what it is being contained in. For example, the shape pf 500mL of water is determined by the shape of the bottle that it is kept in.
Can a volcano change shape?
yes
How does the high water content affect the explosiveness of volcanoes?
High water content can increase the explosiveness of volcanoes because it promotes the formation of steam and gas bubbles in magma, building up pressure that can lead to explosive eruptions. When water interacts with magma, it can cause rapid expansion and fragmentation of the magma, creating explosive eruptions with ash clouds and pyroclastic flows.
