Correct. Basaltic magma usually has a low gas content. Because of this, eruptions involving it are usually effusive or only mildly explosive.

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 is the difference between basaltic magma and silicic magma?

Granitic rocks are intrusive, which means they crystallized underground. Basaltic rocks are extrusive, meaning they crystallized above ground. Also, basaltic rocks are more mafic, and granitic rocks are more felsic.


What is shield volcanoes lava composed of?

TThe magma is composed of gas and is silica rich.


If basalt is in lava is the volcano explosive?

Basaltic lava tends to be less explosive than other types of lava because it has lower viscosity and gas content. However, the explosiveness of a volcano is influenced by multiple factors including the volcano's history, magma composition, and gas content. While basaltic lava eruptions are typically less explosive, there can be exceptions.

Why is Kilauea volcano non explosive?

Kilauea is a shield volcano fed by gas-poor basaltic magma. It is the gas in the magma that makes eruptions explosive. Kilauea has occasionally produced explosive eruptions when magma cam in contact with water.


Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?

An intrusion of basaltic magma would likely cause greater contact metamorphism compared to an intrusion of rhyolitic magma. Basaltic magma has higher temperatures and higher fluidity, allowing it to heat surrounding rocks more effectively and induce more intense metamorphic changes.
