Most earthquakes occur along:

A) plate boundaries
B) continental margins
C) major rivers
D) lines parallel with Earth's magnetic field

Plate Boundaries

The edges or borders where two tectonic plates meet, which can be characterized by different types of movements leading to various geologic processes and phenomena.

Continental Margins

The boundary regions between the landmasses and the ocean basins, including the continental shelf, slope, and rise.

Major Rivers

Large, significant rivers that have considerable length, water volume, and drainage area, playing crucial roles in their regional ecosystems and human economies.
