What is a convergent tectonic plate boundary?

A convergent boundary is an area where two or more lithospheric plates collide, leading to processes like subduction and mountain building. These boundaries occur between oceanic and continental crust types over millions of years, resulting in major geological activity such as earthquakes and volcanism. The movement is driven by mantle convection and the pull of dense sinking slabs.

What we know

• A convergent boundary is an area on Earth where two or more lithospheric plates collide. [1, 2]
• Subduction occurs when one plate slides beneath another, which can be defined by a plane of earthquakes known as the Wadati-Benioff zone. [2]
• Convergent boundaries take place between oceanic-oceanic, oceanic-continental, and continental-continental lithosphere. [2]
• Collisions at convergent boundaries can lead to volcanism, earthquakes, orogenesis, deformation, and the destruction of lithosphere. [2]

Still open

• The relative importance and interaction of proposed driving factors for plate motion, such as active convection, mantle upwelling, and lunar tidal drag, remain subjects of debate.
