Question

Quizplus · Accepted Answer

Flood and plateau basalts are massive lava flows that cover vast areas of the continents and are associated with fissure eruptions rather than central-vent type volcanoes, which tend to produce smaller volumes of magma. Batholiths are large plutonic igneous bodies that form deep in the crust and are not typically extruded on the surface. Volcanoes with a high silica content tend to produce explosive eruptions rather than the voluminous flows associated with flood and plateau basalts.
