What will happen if the volcano has high vicosity magma but very low gas content?

The result will be a slow extrusion of lava which will either form a thick block lava flow or a lava dome. If the magma is too viscous it may fail to erupt and instead plug the volcano.

What Gas Content does a Shield Volcano have?
Magma in a shield volcano usually has a low gas content.
What might happen if we injected magma in a volcano?
No human endeavour could make or inject magma into a volcano. The magma found in relation to volcanoes is a natural phenomena.
What has to happen for arenal volcano to erupt?
Magma has to enter the magma chamber beneath Arenal.
What conditions make for a violent volcano eruptions?
magma and high silica content
What are the two factors control the explosiveness of a volcano?
The viscosity of the magma and its gas content.
What type of magma does cotopaxi have?
blue the cotopaxi volcano has red magma when turned to rock. it also has a high silica content
Suppose a volcano that is about to erupt contains mafic magma. The mafic magma has a very low silica content. what types of igneous rocks will the volcano most likely form?
basalt
Why do volcanoes happen?
They happen because magma (inside earth) has to get out of the earth so it pushes land out and then magma turns into lava (outside earth). And then a volcano is formed.
What are cinder cone magma chambers made up of?
bhill
What is the relationship between silica or water content of magma and materials ejected from an volcano?
The concentration of silica and water content in magma influence the force with which it is ejected from a volcano. The higher the levels of water and other gasses as well as the more silica it contains, the more explosive the eruption will be.
Does a composite volcano have a high gas content?
Yes. Composite volcanoes often have a high gas content in their magma, which is why they often erupt explosively.
What happen if there is a lot of water present in the magma?
Magma with high water content is more likely to cause an explosive eruption because magma is underground, which means it's under intense pressure, and the water stays dissolved in the magma. When magma quickly rises to the surface, the pressure decreases and other compounds, such as Carbon Dioxide (CO), become gases. As gases expand rapidly an explosion can happen.
