Three types of plate boundary Convergent boundary Divergent boundary Transform boundary. Tectonic plate interactions are classified into three basic types: [1] Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate .
Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction .
The northern margin of the Indian plate forms a convergent boundary with the Eurasian plate, which constitutes the active orogenic process of the Himalayas and the Hindukush mountains. The northeast side of the Australian plate forms a subduction boundary with the Eurasian plate in the Indian Ocean between the borders of Bangladesh and Burma ...
Convergent boundary – Region of active deformation between colliding tectonic plates; Divergent boundary – Linear feature that exists between two tectonic plates that are moving away from each other; Extensional tectonics – Geological process of stretching planet crust
An ocean basin may be formed between the continental margin and the island arcs on the concave side of the arc. These basins have a crust which is either oceanic or intermediate between the normal oceanic crust and that typical of continents; heat flow in the basins is higher than in normal continental or oceanic areas.

The northern and western borders are a divergent boundary while the rest of the borders are transform and convergent boundaries. The Balmoral Reef plate's ocean crust is less than 12 million years old and is spreading between the New Hebrides and Tonga subduction. [5] [6] The plate forms the west central part of the seafloor of the North Fiji ...
