Question

Quizplus · Accepted Answer

Basaltic magma is the most abundant type of erupted at oceanic spreading centers. This is because oceanic spreading centers are locations where new oceanic crust is formed through volcanic activity. Basaltic magma is low in viscosity and erupts relatively easily as compared to other types of magma. It also has a low silica content, which makes it easier to melt and flow. Therefore, the vast majority of lava erupted at oceanic spreading centers is basaltic in composition.
