Question

convection currents move tectonic plates in two locations as described below:
location a: tectonic plates move away from each other
location b: one tectonic plate is forced beneath another
what statement most likely describes the effects of this movement at each location?
location a creates a volcano; location b creates a gap allowing molten material to seep through
location a uplifts and forms a mountain; location b creates a volcano
location a creates a gap allowing molten material to seep through; location b melts and recycles the crust
location a melts and recycles the crust; location b creates new ocean crust

Explanation:

• Location A: When tectonic plates move away from each other (divergent boundary), magma rises to fill the gap. This can lead to the formation of new ocean crust as the magma cools and solidifies.
• Location B: When one tectonic plate is forced beneath another (convergent boundary - subduction zone), the sub - ducted plate melts. This recycled crust can lead to volcanic activity as the molten material finds a way to the surface.

Answer:

Location A melts and recycles the crust; Location B creates new ocean crust.
