5.Based on the discussion, what happens when a continental plate and an oceanic plate collide? A. The edge of the oceanic plate moves down into the mantle. B. Slab pull causes the ocean floor to expand. C. New rock material rises to the surface at the subduction zone. D. Parts of...
New spreading centers primarily develop either by the splitting of intact plates or when regions of plate convergence begin to extend. Both plate splitting and extension of convergent regions occur most often in continental, and not oceanic, lithosphere. Rifts are places where the breakup process ...
Locally, the amount of oceanic heat actually reaching the subglacial cavities is likely to be more strongly constrained by a complex combination of bottom topography, surface buoyancy fluxes, and the convergence/divergence of along-shelf temperature advection, rather than the cross-isobath heat ...
