Explanation:

Question 15

Destructive events change the Earth's surface by breaking down or removing material. A landslide (A) is a destructive event that moves rock/soil. Canyon formation (C) is caused by erosion (destructive) from water. River deposition (B), mountain formation (D), and sand dune formation (E) are constructive (build up) or involve different processes. So A and C are destructive.

Divergent boundaries are where plates move apart. Seafloor spreading (B) occurs here. Mid - ocean ridges (D) form at divergent boundaries. New oceanic crust (E) is created as magma rises. Subduction zones (A) and deep - ocean trenches (C) are at convergent boundaries.

When two oceanic plates move towards each other (convergent boundary), the denser plate subducts. This can cause earthquakes (B) due to plate friction, tsunamis (A) from underwater earthquakes, and volcanic eruptions (E) as magma rises. Rift zones (C) and mid - ocean ridges (D) are at divergent boundaries.

Answer:

A. landslide, C. canyon formation
