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.
What else can I help you with?
How viscosity affect volcanic eruptions?
Viscosity is how thick the magma is and this can impact on how much a volcano erupts and how it flows.
What hapens when a volcano erupts?
Magma comes out
How do you think the location of a volcano affects the magma composition?
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.
How explosively or quietly a volcano erupts is not affected by the what?
How explosively or quietly a volcano erupts is not affected by the location of the volcano itself. Instead, it is primarily influenced by factors such as the composition of the magma, gas content, and the pressure buildup within the magma chamber. These geological characteristics determine whether an eruption will be effusive or explosive, regardless of where the volcano is situated.
What is magma called when it erupts from a volcano?
It is called Lava.
When magma erupts from the volcano what is it called?
This is known as lava.
When magma erupts onto the planets surface what it is called?
When magma erupts onto the planet's surface, it is called lava.
What is magma the erupts onto the surface of the volcano c?
Magma that erupts onto the surface of a volcano is called lava. When magma rises from beneath the Earth's crust and reaches the surface, it flows out during a volcanic eruption. Lava can vary in composition, temperature, and viscosity, affecting its behavior and the type of eruption that occurs. Once it cools and solidifies, it forms volcanic rock, contributing to the structure of the volcano and the surrounding landscape.
What factors determine whether a volcano has a violent or quiet eruption?
A volcano erupts when enough pressure builds up inside of it to unplug it's crater. The stronger the plug, the more force is needed to expel it, which results in a more violent eruption. Also, the stickiness of the lava is a factor. The more sticky the lava, the stronger the eruption.
When does an active volcano erupt?
An active volcano erupts when there is an accumulation of magma beneath the surface that builds up pressure and eventually forces its way out through the volcano's vent. Factors such as the composition of the magma, tectonic activity, and gas content can influence the frequency and intensity of eruptions.
When a volcano erupts does the molten material create magma plateaus?
yes
What happens as magma from beneath the earths surface erupts as a volcano?
which are the following?
