Answer:
1. b. Pacific ocean 2. c. Convergent boundary
Step-by-step explanation:
- From looking at the map places situated at the earthquake epicenters have the most of the earthquakes that occur at the boundary of the Pacific plates and thus this place lies in the ring of fire and as result is dotted with earthquakes of all types and sizes.
- Plate tectonics found her works like a convergent boundary as the S-shaped mid-Atlantic ocean has divergent plate boundary the pacific is shrinking under the North-American plate being denser and hense the collision results in downwards formation of subduction zones under the trenches.
