Describe the process by which metamorphic rock can become sedimentary rock.

when pieces of a metamorphic rock get broken off and get trapped between other layers of rock and become one sedimentary rock.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
