How do ridges and rises differ
WebFeb 17, 2024 · At mid-ocean ridges, plates are spreading apart and magma rises to fill the gaps. Near subduction zones, plates collide, forcing ocean crust down toward Earth’s hot interior, where this crustal material melts, forming magma that rises buoyantly back to the surface and erupts to create volcanoes and seamounts.

WebHow do ridges and rises differ? Ridges are associated with divergence, and rises are associated with convergence. Rises are associated with hotspots, and ridges result from seafloor spreading at divergent plate boundaries. Rises are broader and more gently sloped than ridges. How are oceanic ridges different from oceanic rises quizlet? WebWe would like to show you a description here but the site won’t allow us.
WebFaster spreading ridges like the northern and southern East Pacific Rise are “hotter,” meaning more magma is present beneath the ridge axis and more volcanic eruptions occur. Because the plate under the ridge crest is hotter scientists think that the plate responds to the divergent spreading process more fluidly.
