the hot type
Yes. Felsic magma is very viscous.
Viscous, gaseous magma, usually of high acidity as compared to basalt.
Well, lava and magma can be very very dangerous! Lava is something that you can die in. And magma is still lava. They both can be very dangerous! So I would say it is 90% dangerous.
Viscous and silica-rich magma, such as dacite or rhyolite, often erupts out of dome complexes. Due to its high viscosity, this type of magma tends to form domes and does not flow as easily as basaltic magma.

Yes. Felsic magma is very viscous.
Viscous, gaseous magma, usually of high acidity as compared to basalt.
The magma type for a lava dome is typically viscous and silica-rich. This type of magma often leads to slower, more explosive eruptions that result in the gradual buildup of a dome-shaped feature composed of solidified lava.

Highly viscous felsic magma causes the most violent volcanic eruptions.
Viscous and silica-rich magma, such as dacite or rhyolite, often erupts out of dome complexes. Due to its high viscosity, this type of magma tends to form domes and does not flow as easily as basaltic magma.
Higher viscous magma flows slower and with more difficulty compared to lower viscous magma. This is because higher viscous magma has a higher resistance to flow due to its thicker consistency, which can result in more explosive and violent eruptions.
Highly explosive volcanoes typically have viscous, silica-rich magma known as rhyolitic magma. This type of magma contains high amounts of gas and is prone to causing explosive eruptions due to the trapped pressure within the magma chamber.
Mount Rainier primarily erupts andesitic magma, which is a type of intermediate magma that is thicker and more viscous than basaltic magma. Andesitic magma often leads to explosive eruptions due to its high gas content and tendency to trap pressure.
Thick and slow-moving magma is called "silicic magma." This type of magma is typically high in silica content, making it more viscous and less able to flow easily. It often leads to explosive volcanic eruptions due to the built-up pressure.
