Where oceanic plates are separating, mid-ocean ridges are formed. These underwater mountain ranges occur at divergent plate boundaries, where magma rises from the mantle to create new oceanic crust as the plates pull apart. This process can also lead to the formation of hydrothermal vents, which support unique ecosystems.
You would find a mid-ocean ridge at an oceanic-oceanic plate divergent boundary. This ridge is formed by the spreading apart of the two plates, allowing magma to rise and create new oceanic crust.
The surface feature formed when two plates meet is known as a fault. In some cases mountains can also be formed when two plates collide.
trench
As you move away from a divergent boundary in either direction, new crust is formed through the process of seafloor spreading. This creates new oceanic crust as magma rises to fill the gap created by the separating tectonic plates. Over time, the distance between the plates increases and new oceanic crust is formed.

a trench is formed when 2 oceanic plates collide
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.

Mountains and grass
Subduction zones are formed when oceanic plates slide beneath continental plates. The process leads to the oceanic plate being forced into the Earth's mantle. This can result in the formation of deep oceanic trenches and volcanic activity at the surface.
