25.2 - Earthquakes (10 pts.)

Why do most earthquakes occur along plate boundaries?

• At many divergent boundaries, subduction occurs.

• The crust at plate boundaries is brittle and weak.

• Stress accumulates in rocks where plates collide, separate, or slide past one another.

• At many convergent boundaries, rifting occurs.

Answer explanation

Most earthquakes occur along plate boundaries because stress accumulates in rocks where plates collide, separate, or slide past one another.
