Is galeras volcano cinder composite or shield?
Galeras is a Strato/Composite volcano because of it's gently sloping sides.
Does the composite volcano have high viscosity?
Composite volcanoes typically have higher viscosity lava compared to shield volcanoes, resulting in more explosive eruptions. The high silica content in the magma of composite volcanoes contributes to this higher viscosity. However, the exact viscosity of the lava can vary depending on specific factors such as temperature and gas content.
Does a cinder cone volcano have a high or low gas content?
Cinder cone volcanoes typically have a high gas content due to the gas-rich magma that erupts explosively, creating ash and cinder deposits around the vent.
Is soufriere hills a composite volcano?
It is a composite volcano - also called a stratavolcano.
What type of volcano formation would typically be found under a convergent boundary?
A stratovolcano or composite volcano would typically be found under a convergent boundary. These volcanoes form from the intense pressure and heat generated by the subduction of one tectonic plate beneath another, leading to explosive eruptions due to the high gas content of the magma.

What two properties of magma determine what kind of volcano will form?
The silica content and the gas content of magma are two properties that determine what kind of volcano will form. Magma with low silica content and low gas content tends to form effusive, shield volcanoes, while magma with high silica content and high gas content tends to form explosive, stratovolcanoes.
Does a cinder cone volcano have a high or low gas content?
Cinder cone volcanoes typically have a high gas content due to the gas-rich magma that erupts explosively, creating ash and cinder deposits around the vent.

A stratovolcano or composite volcano would typically be found under a convergent boundary. These volcanoes form from the intense pressure and heat generated by the subduction of one tectonic plate beneath another, leading to explosive eruptions due to the high gas content of the magma.
What are the two factors control the explosiveness of a volcano?
The viscosity of the magma and its gas content.
What Gas Content does a Shield Volcano have?
Shield volcanoes typically have a low gas content due to their low-viscosity lava flows that allow gases to escape easily during eruption. This results in eruptions that are generally less explosive compared to other types of volcanoes.
What are the two factors the control whether a volcano eruption will be explosive or quiet?
The two main factors that control whether a volcano eruption will be explosive or quiet are the viscosity of the magma and the presence of dissolved gases. High viscosity magma (thick and sticky) and high gas content tend to result in explosive eruptions, whereas low viscosity magma (thin and runny) and low gas content lead to quiet eruptions.
What kind of volcanoes have rhyolitic lava?
Rhyolitic magma has a high viscosity content, making it flow slowly. Because of its slow moving liquid rock, it doesn't flow very far from the main vent, producing a very tall composite volcano. Once lava is released from the main vent it flows down the sides of the volcano and hardens. Because it is slow moving, some times it doesn't get all the way to the ground before it hardens, that's why composite volcano's are vary tall. Rhyolitic magma is also high in gas and silica content, making it very explosive.
Does pumice turn to liquid when it leaves a volcano?
No, pumice does not turn into a liquid when it leaves a volcano. Pumice is a type of volcanic rock that forms from frothy lava with high gas content that solidifies quickly, resulting in its porous and lightweight structure.
What type of volcano is mt fuji?
Mount Fuji is a stratovolcano, also known as a composite volcano. This type of volcano is characterized by its steep symmetrical cone shape and explosive eruptions due to the combination of viscous lava and gas-rich magma.
