When oceanic and continental crust collide at a subduction zone, one plate is forced under the other. The angle at which the subducting plate descends is due to which of the following factors?


Answer:
1.the age of the plate being subducted.
2. the density of the plate being subducted.

Older crust subducts at a steeper angle because something about the plate changes over time. Density is the primary factor controlling sudbuction angle.
