The magma beneath Mount St. Helens is typically of low viscosity due to its composition, which is rich in silica and gas. This low viscosity magma allows for gases to escape easily, resulting in explosive eruptions.
It happened because of an overflow of magma.
Mount St. Helens could possibly hold up to 0.3 cubic kilometers of magma in its magma chamber. However, the exact volume can fluctuate based on various factors such as temperature, pressure, and composition of the magma.
Mount St. Helens has a magma chamber that can hold approximately 2 to 5 cubic kilometers of magma. However, the exact capacity can vary due to geological processes and the dynamics of volcanic activity. Since its major eruption in 1980, the volcano has continued to evolve, affecting the size and characteristics of its magma reservoir.
The location of a volcano can affect the magma composition by influencing the source of the magma. Magma composition can vary based on factors like the depth of the magma source, the presence of subducted materials, and the amount of water and gases present. Different locations can have different geological conditions that influence the composition of the magma erupted by a volcano.

it was 2000 digrees faren height
It happened because of an overflow of magma.
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
it is basaltic, granitic i dont know which one but one of them i think
The magma of the Hawaiian volcanoes has a basaltic composition, which means it has a low viscosity (it flows easily) and so can erupt easily without needing too much force behind it. This low viscosity magma cannot hold very much gas and so erupts effusively By contrast, the magma involved in the 1980 eruption of Mount St Helens had a dacitic composition, which has an extremely high viscosity. The high viscosity allows large mounts of gas to be stored in the magma under pressure. When the magma was exposed to lower pressure near the surface, the gas was released and expanded explosively, blasting the magma into ash and pumice.

Magma is not a mineral becauseIt is liquid.It does not have a definite chemical composition.
Sunset Crater was fed by basaltic magma.
