Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge and Pacific Ring of Fire are two examples of divergent plate boundaries.

WebSince the early days of ocean exploration, scientists have been fascinated with understanding the pattern of species distribution throughout the marine environment. This area of scientific study is known as marine … WebMost divergent boundaries are located along mid-ocean oceanic ridges (although some are on land). The mid-ocean ridge system is a giant undersea mountain range, and is the largest geological feature on Earth; at 65,000 km long and about 1000 km wide, it covers …
WebContinental crust is composed of lower density rocks such as granite and andesite. New oceanic crust is created at divergent boundaries that are sites of sea-floor spreading. At divergent boundaries, upwelling of magma along mid-ocean ridges (e.g., Mid-Atlantic … WebStudy with Quizlet and memorize flashcards containing terms like Flux melting most likely occurs at: (A) Mid-ocean ridges. (B) Transform faults. (C) Subduction zones. (D) None of the above, Decompression melting occurs as a result of: (A) Decrease of the confining pressure as the Core rises to shallower depth. (B) Increase of the confining pressure as …
WebThe composition of the two types of crust differs markedly, with mafic basaltic rocks dominating oceanic crust, while continental crust consists principally of lower-density felsic granitic rocks. In plate tectonics, Earth’s outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. WebLarge convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading centers, creating divergent plate boundaries. As the plates …
WebMagma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created Explain Convergent plate boundaries? When two plates come together, it …
