During the process of mountain building, earthquakes sometimes occur along continental-continental convergent boundaries. Which statement best describes the motion of the plates along these boundaries that causes the earthquakes?

Question

The plates push apart from each other with no subduction.
Subduction occurs with the less-dense plate sinking below the other plate.
Subduction occurs with the more-dense plate sinking below the other plate.
The plates smash together with no subduction.

Answer 1

The statement that best describes the motion of the plates along continental-continental convergent boundaries that causes the earthquakes is:

The plates smash together with no subduction.

In continental-continental convergent boundaries, two continental plates collide, and since neither plate is significantly denser than the other, subduction typically does not occur. Instead, the plates crumple and fold, leading to mountain building and often resulting in earthquakes.
