Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle.
In geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction , whereby the subduction zone is destroyed, mountains produced, and two continents sutured together.
This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed] Orogenic belts occur where two continental plates collide and push upwards to form large mountain ranges. These are also known as collision boundaries. Subduction zones occur where an oceanic ...
Tectonic plates are composed of the oceanic lithosphere and the thicker continental lithosphere, each topped by its own kind of crust. Along convergent plate boundaries, the process of subduction carries the edge of one plate down under the other plate and into the mantle. This process reduces the total surface area (crust) of the Earth.

There are two types of continental margins: active and passive margins. [1]Active margins are typically associated with lithospheric plate boundaries. These active margins can be convergent or transform margins, and are also places of high tectonic activity, including volcanoes and earthquakes.
The southern part of Zealandia, which is to the east of this boundary, is the plate's largest block of continental crust. [citation needed] Hillis and Müller are reported to consider the Bird's Head plate to be moving in unison with the Pacific plate, [4] but Bird considers them to be unconnected. [5]
