Question

Plate tectonics is the theory explaining the structure of the earth's crust and the resulting features and processes of the interaction of the plates that move slowly over the underlying mantle. A mid-ocean ridge is a feature that results in ocean to ocean divergent boundary zones. How is a mid-ocean ridge a resulting feature?
A. The plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge.
B. Mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones.
C. The plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge.
D. The rising convection current below the oceanic lithosphere lifts the lithosphere as the plates move apart.

Answer 1

The answer is "The rising convection current below the oceanic lithosphere lifts the lithosphere as the plates move apart." which is letter D. Convection current moves the plate away from each other due to the heat pressure that circulates beneath the lithosphere. The gap between the divergent plane will create the mid-ocean ridges.

Answer 2

Answer:

D. The rising convection current below the oceanic lithosphere lifts the lithosphere as the plates move apart.

Explanation:

Plate tectonic is a theory that explains how tectonic plates are moving, These plates are diverging , converging or even moving past each other. The Interaction of this earth tectonic plates cause a slow movement on the underlying mantle .

The boundary where plates moves apart is known as the divergent boundary. The divergent boundary is prevalent in the oceanic crust . This boundary mostly involve ocean ocean separation or spreading. Mantle materials from the mantle region upwells to the sea floor during spreading through the mid oceanic ridge. The rising convection current below the oceanic lithosphere or crust lifts the crust and causes a spreading or moving apart of the plate. The mid oceanic ridge is usually formed and this where mantle materials are likely to be exposed to the sea floor.
