Compare and contrast explosive and effusive eruptions. Include their locations, the chemical composition of the magma, and the landforms they typically produce
What will be an ideal response?
Effusive eruptions are outpourings of low-viscosity magma that produces enormous volumes of lava. The basaltic rock is low in silica (less than 50%) and rich in iron and magnesium. Effusive eruptions pour out on the surface with relatively small explosions and few pyroclastics. Effusive eruptions may come from a single vent or from a flank of a volcano through a side vent or even fissures.
Explosive eruptions are violent explosions of magma, gas, and pyroclastics driven by pressure build-up in a magma conduit. The magma is thicker and more viscous than effusive magma.
