Correct. Basaltic magma usually has a low gas content. Because of this, eruptions involving it are usually effusive or only mildly explosive.
Basaltic magma is low in silica compared to andesitic or granitic magma.
Baslatic magma is 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.
basaltic
TThe magma is composed of gas and is silica rich.
basaltic with little gas content

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.
basaltic
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.

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.
basaltic,andesitic,rhyolitic
Basaltic magma usually forms a black rock.
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.
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.
