Ridges of buoyant oceanic crust form at diverging oceanic plate boundaries.
convergent
A mid-ocean ridge forms at a divergent boundary when two oceanic plates move apart. This boundary is characterized by the upwelling of magma from the mantle, which solidifies to create new oceanic crust. This process results in the formation of a continuous underwater mountain range.
You are a mid-ocean ridge that forms when tectonic plates move apart and new oceanic crust is created through volcanic activity. This process is known as seafloor spreading, and it results in the formation of new oceanic crust at the mid-ocean ridge.
Oceanic plates are primarily made of basalt, which is a type of volcanic rock that forms from the cooling and solidification of magma on the ocean floor. Basalt is dark in color and has a fine-grained texture.

At diverging plate boundaries, new oceanic crust forms through seafloor spreading. Magma rises to the surface and solidifies, creating mid-ocean ridges. As the plates move apart, they create new oceanic crust, which can lead to the formation of rift valleys.
The mechanism responsible for producing new oceanic crust between two diverging plates is seafloor spreading. Magma rises up from the mantle at mid-ocean ridges, solidifies upon reaching the seafloor, and forms new crust. As the plates move apart, this process continuously adds new material to the ocean floor.

Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.
The mechanism responsible for producing new seafloor between two diverging plates is seafloor spreading. Magma rises from the mantle to fill the gap created by the plates moving apart, solidifies upon contact with seawater, and forms new oceanic crust. This process results in the continuous growth of the ocean floor.
convergent
When two oceanic plates collide, a deep ocean trench is formed due to one plate being pushed under the other in a process known as subduction. This subduction zone can create volcanic activity and earthquakes in the region.

1. Oceanic trenches. 2. Volcanic islands. 3. Volcanic mountains. and 4. Volcanic arcs.
Basalt is found in abundance on the Earth's oceanic crust, making up the majority of the ocean floor. It is also present in some continental areas, particularly in regions with volcanic activity such as Hawaii or Iceland. Additionally, basalt can often be found in areas where tectonic plates are diverging, such as along mid-ocean ridges.
