Chp 3 Review

A community of marine organisms that depend on the specialized environment found at rift zones in the ocean floor is?

• rift community

• rift zones

• oceanic basaltic crust

• fracture zones

A process by which magma driven by convection currents is turned back by the lithosphere, moves laterally (meaning sideways) and descends, causing lateral (sideways) movement of earth's crust?

• subduction zones

• rift zones

• seafloor spreading

• escarpments

Linear region of unusually irregular ocean bottom that runs perpendicular to ocean ridges?

• transform fault

• fracture zones

• continental drift

The movement of continental masses as a result of seafloor spreading?

• midocean ridge

• rift community

• escarpments

• continental drift

A nearly continuous line of cliffs with sharp vertical drops?

• escarpments

• theory of plate tectonics

• seafloor spreading

• bathygraphic features

New earth crust formed when magma erupting from midocean ridges cools?

• bathygraphic features

• rift community

• oceanic basaltic crust

• fracture zones

A long mountain range that forms along cracks on the ocean floor

• fracture zones

• rift zones

• seafloor spreading

• midocean ridge

Region of the ocean floor where old crust sinks to the earth's core and is recycled

• fracture zones

• subduction zones

• transform fault

• midocean ridge

Theory stating that the movement of continental masses is the result of the movement of the plates on which they rest

• oceanic basaltic crust

• rift zones

• bathygraphic features

• theory of plate tectonics

Fault occurring in regions where parallel, lithospheric plates slide past each other
