WebMar 13, 2024 · The densest magma sinks near the bottom of the chamber. Over millions of years, many magma chambers simply cool to form a pluton or large igneous intrusion. If a magma chamber encounters an enormous amount of pressure, however, it may fracture the rock around it. The cracks, called fissures or vents, are tell-tale signs of a volcano.

WebJul 7, 2024 · A divergent boundary occurs when two tectonic plates move away from each other . 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. WebEach layer is made of a different kind of material: the crust consists of relatively low-density rocks (like granite and basalt), the mantle is made of more dense rock, and the core consists of iron. There are two kinds of crust: oceanic and continental. Oceanic crust is somewhat more dense than continental crust.

WebThe prefix "di" means two or apart. Divergent Plate Boundary = where two lithospheric plates are moving apart. Divergent Oceanic-Oceanic. Divergent Oceanic-Oceanic = area where two oceanic plates are pulling apart. Magma from the mantle is rising and splitting the plates apart. Results in: volcanoes, earthquakes, and mid-ocean ridges.
