In convergent and destructive plate boundaries, two plates collide into each other forming breaks in the Earth which then lead to landforms. This can include mountains or mountain ranges. Also convergent and destructive plate boundaries can create volcanoes and a variety of other landforms.
On the other hand, in divergent and constructive plate boundaries, two tectonic plates retract from each other. This forms mid-ocean ridges, island arcs and again, a variety of other landforms, not yet listed.
The location and type of tectonic plate, interferes with the creation of landforms.
Here are some of the different types and locations that lead to the creation of landforms via tectonic plates.
Fold Mountains:
Fold mountains are located on a compressional plate. In this part, two plates move as one and often create fold mountains. This is usually done with a continental and oceanic plate. The process starts with the forcing of sedimentary rocks upwards making mountain folds. Fold mountains are found along the edges of continents as this is the location of the highest number of sedimentary rock piles. Thus meaning when tectonic plates collide, layers of accumulated rock crumble and create fold mountains.
Ocean Trenches:
Ocean trenches are formed in one of two ways: either via two tectonic plates colliding into each other or from continental land masses colliding with the moving sea floor. Potentially this can create a trench, which could be found on the sea floor side. These trenches are long and narrow and are located in the deepest section of the ocean.
Island Arcs:
Island arcs are apart of the subduction process. Thus meaning when an oceanic plate collides with another tectonic plate, specifically oceanic; it could possibly lead to volcanoes being formed.
Ocean Ridges:
Ocean ridges are a section of the divergent boundaries (see paragraph 1). Because of the pressure and force used, when collision occurs it creates a new crust, thus meaning magma is forced up from the mantle. The movement of tectonic plates then transports the new crust. It retracts from the boundary of the ocean ridge.
