What is source material for andesitic magma?
Andesitic magma is typically sourced from the partial melting of subducted oceanic crust and overlying mantle at convergent plate boundaries. This process results in the formation of a magma with intermediate silica content, giving rise to andesitic volcanic rocks.
Does Andesitic magma have both an intermediate gas content and explosiveness?
Andesitic magma typically has an intermediate gas content, resulting in eruptions that can be explosive, but not as violently explosive as magmas with higher gas contents like rhyolitic magma. The explosiveness of Andesitic magma eruptions can be influenced by factors such as the speed of gas release and the presence of water or other volatiles.
Where is andesitic magma found?
Andesitic magma is commonly found in subduction zones where oceanic crust is being forced beneath continental crust. These environments are typically associated with volcanic arcs and stratovolcanoes. Examples of where andesitic magma is found include the Andes Mountains in South America and the Cascades in the western United States.
What are the 3 types of magma?
basaltic magma ,Andesitic magma and Rhyolitic magma
Is basaltic or andesitic magma hotter?
Basaltic magma is hotter than andesitic magma. Basaltic magma typically has temperatures ranging from 1000°C to 1200°C, while andesitic magma has temperatures around 800°C to 1000°C.

What types of volcanoes are created when andesitic magma erupts?
Andesitic magma will result in the formation of a stratovolcano, also called a composite volcano.
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 is source material for andesitic magma?
Andesitic magma is typically sourced from the partial melting of subducted oceanic crust and overlying mantle at convergent plate boundaries. This process results in the formation of a magma with intermediate silica content, giving rise to andesitic volcanic rocks.
How does andesitic rise to the surface?
magma rises and cools
What type rock can form magma andesitic?
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.
Does Andesitic magma have both an intermediate gas content and explosiveness?
Andesitic magma typically has an intermediate gas content, resulting in eruptions that can be explosive, but not as violently explosive as magmas with higher gas contents like rhyolitic magma. The explosiveness of Andesitic magma eruptions can be influenced by factors such as the speed of gas release and the presence of water or other volatiles.
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.
Where is andesitic magma found?
Andesitic magma is commonly found in subduction zones where oceanic crust is being forced beneath continental crust. These environments are typically associated with volcanic arcs and stratovolcanoes. Examples of where andesitic magma is found include the Andes Mountains in South America and the Cascades in the western United States.
What are the three main types of magma what factor determines these classifications?
The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.
