Which statement correctly

Question

compares earthquakes at mid�ocean ridges and plate
boundaries?
The depth of an
earthquake’s focus is
greater at plate
boundaries.
Earthquakes occur at
mid-ocean ridges, but
not at plate
boundaries.
The depth of an
earthquake’s focus is
greater at mid-ocean
ridges.
Earthquakes occur at
plate boundaries, but
not at mid-ocean
ridges.

Answer 1

The correct statement is: The depth of an earthquake’s focus is greater at plate boundaries.

This is because earthquakes at mid-ocean ridges typically occur at shallower depths, while those at some plate boundaries, especially convergent boundaries, can occur at much greater depths. Earthquakes do occur at both mid-ocean ridges and plate boundaries, so the other statements are incorrect.
