Question

1. where do unusually deep earthquakes occur?

near the edges of some continents
only in oceanic plates
randomly around the world
in continental plates along mountain ranges

Explanation:

Deep earthquakes occur in subduction zones where oceanic plates dive beneath continental plates (or other oceanic plates). These zones are often near continental edges (e.g., the Pacific Ring of Fire). They are not random, not limited to oceanic plates alone, nor only in continental mountain ranges.

Answer:

A. near the edges of some continents
