Question
For each of the labeled features, match the name of the feature with the appropriate description of how that feature formed.
Movement of a plate over a hot spot results in a linear chain of volcanic islands and seamounts.
Two oceanic plates diverge, allowing mantle to rise, melt, and form new oceanic crust.
Formed where two oceanic plates converge, and melting caused by the subducted plate results in volcanoes on the overriding plate.
A rising plume of mantle melts and causes melting of adjacent lithosphere, and magma erupts onto the seafloor.
Formed by bending down of a slab as it enters a subduction zone.
Sediment is transported by turbidity currents from the edge of the continent into deeper water.
Cooling of the lithosphere causes subsidence of oceanic crust, which is then covered by deep-water sediments.
Differences in the age of seafloor cause oceanic crust on one side of this feature to be higher in elevation than oceanic crust on the other side, but the feature is not a plate boundary.
Migration of an island arc and trench causes oceanic crust behind the arc to stretch, rift, and spread.
A broad area of continental crust that has been thinned and overlain by marine sediments.
