Question

Label the: oceanic plate, continental plate, the subduction zone, asthenosphere, divergent boundary, and draw a convention current showing the movement of magma.

Answer 1

The oceanic plate is the thinner and denser plate that is subducted under the continental plate at a convergent boundary, forming a subduction zone. The asthenosphere is the layer of the mantle below the lithosphere where magma flows in convection currents[1]. A divergent boundary occurs when two plates move away from each other, allowing magma to rise and form new crust on the lithosphere. A convention current showing the movement of magma would be drawn as arrows pointing upwards from the asthenosphere towards the lithosphere at a divergent boundary.
