What best describes the composition of the magma that erupts at Mount Pinatubo in the Phillippines?
The magma that erupts at Mount Pinatubo is mainly dacitic in composition, which is a type of intermediate magma that is rich in silica. This type of magma typically leads to explosive eruptions due to its high viscosity and gas content.
What type of rock does magma make?
Magma cools and solidifies to form igneous rocks such as granite, basalt, and obsidian depending on the cooling rate and mineral composition.
What is formed from the crystallization of magma?
When magma cools and solidifies, it forms igneous rocks such as granite, basalt, or obsidian. The specific type of rock that forms depends on variables such as the composition of the magma, cooling rate, and environment in which it solidifies.
What statement best describes the composition of magma?
Magma is molten rock beneath the earth, usually with some trapped gasses in it. The composition of magma varies, but the most abundant compounds include: Silica (SiO2), aluminum oxide (Al2O3), calcium oxide (CaO), sodium oxide (Na2O), magnesium oxide (MgO), potassium oxide (K2O), and iron oxide (FeO and Fe2O3). Trapped gasses, which make up a smaller proportion include water (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2).
What type of magma is produced by mount Bromo?
Mount Bromo typically produces andesitic magma, which is intermediate in composition between basaltic and rhyolitic magma. Andesitic magma is known for its moderate silica content, resulting in eruptions that can be relatively explosive.
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.
Why is magma not a mineral?
Magma is not a mineral becauseIt is liquid.It does not have a definite chemical composition.
What is Sunset Crater's magma composition?
Sunset Crater was fed by basaltic magma.
What magma composition does Mt Hekla have?
Mt. Hekla in Iceland has a composition of intermediate to felsic magma, which is rich in silica, giving it a higher viscosity compared to basaltic magma. This type of magma can lead to explosive eruptions.
What type of magma is closer to intrusive rocks?
magma can be classified into two,magma of granitic composition(originates from lower continental crust) and magma of basaltic composition (which originates from upper mantle).Both can form intrusive rocks.
3 ways composition of magma can be modified?
The composition of magma can be modified by the addition of new material, such as when magma assimilates surrounding rock as it rises to the surface. Magma composition can also be altered through fractional crystallization, where minerals crystallize and separate from the remaining melt. Mixing of different magma batches can further modify composition through hybridization.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
What is the magma composition of Galeras?

The average composition of rocks comprising a large composite cone or stratovolcano is similar to what magma?
The average composition of rocks in a large composite cone or stratovolcano is similar to andesitic magma. Andesitic magma is intermediate in composition between basaltic and rhyolitic magma, containing elements such as silica, magnesium, and iron. This magma type is responsible for the explosive eruptions characteristic of stratovolcanoes.
Why does the composition of magma change as it rises through the crust?
The composition of magma changes as it rises through the crust due to various processes such as assimilation, crystallization, and mixing. As magma ascends, it can incorporate surrounding rock material which influences its composition. Additionally, as magma cools and solidifies, certain minerals crystallize out of the melt, altering its chemical makeup.
What is the lava composition for surtsey?
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.
