Destructive plate boundaries are:

• A. A boundary where plates move apart
• B. A convergent boundary where two plates collide
• C. A boundary where plates slip past each other
• D. A boundary where magma intrudes at the surface

Answer: (B)

Destructive plate boundaries are subduction zones where one tectonic plate sinks beneath another as they collide, recycling crust back into the mantle. This is described as a convergent boundary where two plates collide. The interaction produces deep earthquakes and volcanic activity, often forming a trench and a volcanic arc. Moving apart describes divergent boundaries, while sliding past each other describes transform boundaries. Magma intruding at the surface relates to volcanic activity but isn’t itself a boundary type.
