Explanation:

To solve this, we analyze each model (L, M, N, O) and match with land features/geologic processes:

• Model L: Shows a convergent boundary (one plate subducting under another). Ocean Trenches/Volcanoes form at convergent boundaries (ocean - continental or ocean - ocean convergence). So Model L matches Ocean Trench / Volcanoes.
• Model M: Shows a convergent boundary with continental plates colliding (no subduction, just collision). Continental Folded Mountains form from this (e.g., Himalayas). So Model M matches Continental Folded Mountains.
• Model N: Shows a divergent boundary (plates moving apart). Rift Valleys (on land) or Mid - Ocean Ridges (underwater) form here. So Model N matches Rift Valley / Mid - Ocean Ridge.
• Model O: Shows a transform boundary (plates sliding past each other). Faults and strong earthquakes occur at transform boundaries (e.g., San Andreas Fault). So Model O matches Faults / Strong Earthquakes.

Answer:

• Model L: Ocean Trench / Volcanoes
• Model M: Continental Folded Mountains
• Model N: Rift Valley / Mid - Ocean Ridge
• Model O: Faults / Strong Earthquakes
