When continental lithosphere converges with oceanic lithosphere, the oceanic lithosphere sinks into the mantle. This happens because the oceanic lithosphere is __________ than the continental lithosphereGroup of answer choicesiron-rich and therefore densersilicon-rich and therefore denseriron-rich and therefore less densesilicon-rich and therefore less dense

Crust is not subducted at this kind of boundary.Group of answer choicesOcean-ocean convergenceOcean-continental convergenceContinental-continental convergenceNone of the above, all crust is subducted into the mantle.

The lithosphere is broken up into tectonic plates. Choose two things that the theory of plate tectonics helps explain.

What is the lithosphere?1 pointA) the plates that make up the crust and the upper part of the mantleB) the plates that make up the crustC) the upper part of the mantleD) large, flat stones sitting on top of malleable magmaClear selection

What happens when an oceanic plate converges with a continental plate?1 pointA) The denser oceanic plate slides under the less dense continental plate.B) The less dense oceanic plate slides under the denser continental plate.C) The less dense oceanic plate slides past the denser continental plate.D) The denser oceanic plate slides on top of the less dense continental plate.

In the tectonic cycle, new but recycled lithosphere rises to the ground at boundaries and can be subducted at boundaries.
