Correct Answer: three

Solution : The correct answer is three .

The plate movements on Earth are classified into three main types based on the relative motion of tectonic plates. Divergent boundaries involve plates moving apart, forming new oceanic crust and rift valleys. Convergent boundaries see plates colliding, leading to subduction, trenches, volcanic arcs, and mountain ranges. Transform boundaries involve horizontal sliding, causing earthquakes. Each boundary type plays a crucial role in Earth's dynamic tectonic processes.
