What boundary describes plates moving away from each other?

• A. Divergent Plate Boundaries
• B. Transform Plate Boundaries
• C. Convergent Plate Boundaries
• D. Subduction

Answer: (A)

Movement direction defines boundary types. When two tectonic plates move apart, mantle magma rises to fill the gap and solidifies to form new crust. This is a divergent boundary, seen at mid-ocean ridges and some rift valleys. Transform boundaries occur where plates slide past one another; convergent boundaries are where plates collide; subduction is the sinking of one plate beneath another, usually at convergent zones. So, plates moving away from each other describe a divergent boundary.
