Andesitic magma typically forms in subduction zone environments, where oceanic crust is forced beneath continental crust. This process leads to the melting of both the subducting slab and the overlying mantle, resulting in the generation of andesitic magma. The primary rock types associated with this process are basaltic rocks, which can partially melt and contribute to the formation of andesitic magma through fractional crystallization and mixing with other magma types.
What else can I help you with?
Are pyroclasts formed by basaltic magma or andesitic magma?
Pyroclasts can be formed by both basaltic and andesitic magma. Basaltic magma typically forms pyroclastic materials like scoria and ash, while andesitic magma can produce a variety of pyroclasts including volcanic bombs and pumice. The type of pyroclasts produced depends on factors such as the composition of the magma and the eruption style.
What type of magma flows from Mount Rainier?
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.
What type of lava forms mt hood?
Mt. Hood is primarily composed of andesitic lava, which is intermediate in composition between basaltic and rhyolitic lavas. Andesitic lava is characterized by its viscosity and tendency to form lava domes, lava flows, and pyroclastic flows.
What does magma that is blasted into the air form when it hardens?
When magma is blasted into the air, it cools and solidifies to form volcanic rock, such as lava bombs, volcanic ash, and tuff. The specific type of rock depends on the composition of the magma and the cooling process.
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.
What is the type of magma contain a lot of silica and water vapor is?
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
Are pyroclasts formed by basaltic magma or andesitic magma?
Pyroclasts can be formed by both basaltic and andesitic magma. Basaltic magma typically forms pyroclastic materials like scoria and ash, while andesitic magma can produce a variety of pyroclasts including volcanic bombs and pumice.

What type of magma flows from Mount Rainier?
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.
What type of magma does the eyjafjallajokull produce?
Eyjafjallajökull volcano in Iceland produces andesitic magma, which is a type of intermediate magma that has a silica content between basaltic and rhyolitic magmas. This type of magma can lead to explosive eruptions due to its high viscosity, gas content, and tendency to form pyroclastic flows.
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.
What type of lava forms mt hood?
Mt. Hood is primarily composed of andesitic lava, which is intermediate in composition between basaltic and rhyolitic lavas. Andesitic lava is characterized by its viscosity and tendency to form lava domes, lava flows, and pyroclastic flows.
What are examples of magma?
Examples of magma include basaltic magma, andesitic magma, and rhyolitic magma. Basaltic magma is the most common type and is associated with oceanic volcanic activity. Andesitic magma has intermediate silica content and is found at convergent plate boundaries. Rhyolitic magma is highly viscous and contains high amounts of silica, commonly found in continental volcanic regions.
What is the difference of andesitic and andesite?
Andesite is a type of extrusive igneous rock with moderate levels of silica. Andesitic is an adjective used to describe volcanic material with the composition of andesite. For example, andesitic lava will cool to form andesite.
What type of rock is made from hot magma?
Rocks that form when hot magma solidifies are igneous rocks.
What type pf magma does mt Cleveland have?
Mt. Cleveland has felsic lava, high in silica.
What type of magma does mount shasta have?
Mount Shasta typically has andesitic magma, which is a type of intermediate magma that is common in subduction zone environments. This type of magma is rich in silica and forms from the partial melting of both oceanic and continental crust.
What type of rock contains lava or magma?
The type of rock that contains lava or magma is an igneous rock.
