What are the three main types of plate boundaries?

• A. Convergent, divergent, and transform boundaries
• B. Divergent, subduction, and fault lines
• C. Oceanic, continental, and tectonic
• D. Transform, oceanic, and continental

Answer: (A)

The three main types of plate boundaries are convergent, divergent, and transform boundaries. Convergent boundaries occur where two tectonic plates move towards each other, often resulting in one plate being forced beneath the other, which can lead to the formation of mountains, trenches, or volcanic activity. Divergent boundaries are formed when two plates move apart from one another, creating new crust as magma rises to the surface, typically seen in mid-ocean ridges. Transform boundaries occur where plates slide past each other horizontally, causing friction and resulting in earthquakes. This classification is fundamental in understanding geological processes and the resulting features on Earth’s surface. Other options may refer to specific processes or geological features, but they do not encompass the broad categories recognized in plate tectonics theory.
