Web5 apr. 2024 · Oceanic plates are mafic in nature, composed of basalt rock and its coarse-grained equivalent, gabbro, both rich in iron, magnesium and calcium. In contrast, continental plates are felsic in nature, dominated by granitic rock with its abundant silica, aluminum, sodium and potassium. Web6 feb. 2008 · The Earth’s crust is like cracked pottery. Pressure in layers below causes these shards to shift at the fracture. Subterranean forces associated with volcanoes can also cause a once-familiar mountaintop to bulge as lava tries to push to the surface.
