Imagine a mountain climber dangling from a rope off a cliff her climbing partner holds the other end of the rope trying hard to keep the mountain climber from sliding down if the dangling climber moves downward she’ll pull her partner sideways. how does the motion of the climbers compare to the motion of an oceanic plate that is sinking into the mantle ?

The portion of the oceanic plate that sinks into the mantle pulls downward on the upper portion of the plate that is still nearly parallel to Earth’s surface.

Explanation:

PLATO exact answer.

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.
