Question

most earthquakes happen:
a. near active margins.
b. near regions with no subduction.
c. in a ring around the atlantic ocean.
d. in the middle of continents.

Explanation:

Earthquakes occur due to the movement of tectonic plates. Active margins are where tectonic plates interact (e.g., subduction zones). Subduction (where one plate goes under another) is a common cause of earthquakes. The "Ring of Fire" (around the Pacific Ocean, not Atlantic) has many earthquakes. Middle of continents is relatively stable. Regions with no subduction have less tectonic activity causing earthquakes.

Answer:

A. near active margins.
