At which plate boundary do two plates move toward each other?

• A. Convergent boundary
• B. Divergent boundary
• C. Transform boundary
• D. Ridge boundary

Answer: (A)

Two tectonic plates moving toward each other is a convergent boundary. When they collide, one plate may dive beneath the other in subduction, or two continental plates may crumple upward to form mountains, leading to features like trenches, volcanic arcs, and mountain ranges. Divergent boundaries have plates moving apart, forming ridges and rift valleys; transform boundaries involve sliding past one another horizontally, causing earthquakes. Ridgelike features arise at divergent boundaries rather than indicating a separate boundary type. So, the described motion corresponds to a convergent boundary.
