Which of the following landforms is created by divergent faults?

mountains
deltas
mid-ocean ridges
beaches

The correct answer is "mid-ocean ridges".

Explanation:

Mid-ocean ridges are underwater systems that are seismically active and most of the times have upwelling of magma that causes seafloor spreading. These systems are created by divergent faults located in oceanic plates, causing the formation of submarine mountains which are probably seismic active as mid-ocean ridges. One of the most important mid-ocean ridge is the Mid-Atlantic Ridge located at the bottom of the Atlantic Ocean.
