How does a continental rise form

WebMay 1, 2024 · As plates converge, one plate may move under the other causing earthquakes, forming volcanoes, or creating deep ocean trenches. Where plates diverge from each other, molten magma flows upward between the plates, forming mid-ocean ridges, underwater volcanoes, hydrothermal vents, and new ocean floor crust. WebPlates are constantly in motion, and move about 3 cm (a little over an inch) per year because of slow convection currents in the mantle due to Earth’s internal heat and pulling and pushing on the plates as they form, cool and sink back into the mantle.
