Lavas, particularly basaltic ones, come in two primary types: pahoehoe (pronounced ‘paw-hoey-hoey”) and aa (pronounced “ah-ah”). Both names, like a number of volcanological terms, are of Hawaiian origin. A third type, pillow lava, forms during submarine eruptions.
Where on the ocean floor would you find basaltic magma being extruded?
Basaltic magmas most commonly erupt on the ocean floor at places where two tectonic plates move away from each other. 1. Such places are called spreading centers or mid-ocean ridges.
What can cause basaltic magma to erupt explosively?
When this magma reaches the surface, the gas bubbles will have a high pressure inside, which will cause them to burst explosively on reaching atmospheric pressure. This will cause an explosive volcanic eruption and the production of pyroclastic material.
