Basalt And Granite In Earth S Layer

More than 90 of all volcanic rock on earth is basalt and the eruption of basalt lava is observed by geologists at about 20.

Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate it is composed of the upper oceanic crust with pillow lavas and a dike complex and the lower oceanic crust composed of troctolite gabbro and ultramafic cumulates. The heat of the cooling rock would completely melt any. ˈ b æ s ɔː l t ˈ b æ s əl t is a mafic extrusive igneous rock formed from the rapid cooling of lava rich in magnesium and iron exposed at or very near the surface of a terrestrial planet or a moon.

Granite and basalt are both igneous rocks they are formed from magma extruded into another rock layer or from expulsion from a volcano. Basalt is a very important rock. Although basalt is much less common on continents lava flows and flood basalts underlie several percent of earth s land surface.

The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.
