Confusing Convergent, Divergent, and Transform Boundaries

Students label a plate boundary by the landform they remember instead of by the direction the plates move.

Quick check

Why students make it

Many diagrams show mountains, trenches, ridges, and earthquakes all at once, so students memorize pictures instead of motion. They may also think every boundary with earthquakes is the same type.

The rule done right

Convergent boundaries move toward each other, divergent boundaries move away from each other, and transform boundaries slide past each other. Identify the boundary from plate motion first, then connect it to common features.
