1. 1. Draw a subduction zone in which an oceanic plate collides with a continental plate.
Label the following on your sketch: the oceanic plate, the continental plate, location

crust and the mantle and the boundary between the lithosphere and the asthenosphere.
Draw arrows to show the direction of motion of each of the two plates.
