WebDec 25, 2024 · Explain how ocean ridges and trenches are formed. The upwelling of lava from the asthenosphere presses on thin areas of oceanic crust triggering them to thicken … WebVolcanism in northwestern B.C. (Figures 4.5 and 4.6) is related to continental rifting. This area is not at a divergent or convergent boundary, and there is no evidence of an underlying mantle plume. The crust of northwestern B.C. is being stressed by the northward movement of the Pacific Plate against the North America Plate, and the resulting ... how to shape your eyebrows with wax strips

WebThe Mid-Atlantic Ridge is the longest mountain chain on Earth. These ridges are spreading centers or divergent plate boundaries where the upwelling of magma from the mantle creates new ocean floor. Deep-sea trenches are long, narrow basins which extend 8-11 km below sea level. Trenches develop adjacent to subduction zones, where oceanic ... WebNov 7, 2024 · Trenches are long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another. The deepest parts of the ocean are found in trenches—at more than 35,000 feet (nearly 11,000 … WebThe top limb of the convection cell moves horizontally away from the ridge crest, as does the new seafloor. The outer limbs of the convection cells plunge down into the deeper mantle, dragging oceanic crust as well. This takes place at the deep sea trenches. The material sinks to the core and moves horizontally. notify barclays of going abroad
