Question

question 3
convection currents in the mantle are the force that drives the movement of the tectonic plates. where on the oceanic crust does molten magma reach the surface and create new crust as the plates move apart?
select one:
○a. volcanos
○b. mid - ocean ridges
○c. subduction zones
○d. trenches

Explanation:

Mid-ocean ridges are divergent plate boundaries where tectonic plates move apart. Molten magma rises from the mantle to the surface here, cooling and solidifying to form new oceanic crust. Volcanoes can form in multiple settings (not just where new crust is created at diverging ocean plates), subduction zones are where crust is destroyed, and trenches are deep areas at subduction zones.

Answer:

b. Mid-ocean ridges
