New oceanic crust is created at divergent boundaries, where tectonic plates move apart, allowing magma to rise from the mantle and solidify at mid-ocean ridges. Conversely, oceanic crust is destroyed at convergent boundaries, where one tectonic plate subducts beneath another, often leading to the formation of deep ocean trenches. This process recycles oceanic crust back into the mantle, balancing the creation of new crust at divergent boundaries.

The type of plate boundary where oceanic crust is destroyed is called a convergent boundary, specifically a subduction zone. At these boundaries, one tectonic plate, typically oceanic, is forced beneath another plate, which can be either oceanic or continental. This process leads to the formation of deep ocean trenches and can result in volcanic activity and earthquakes. An example of this is the boundary between the Nazca Plate and the South American Plate.
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 two types of Crust is the Continental Crust and the Oceanic Crust.

Continental crust is the thicker, less dense, and older type of crust found beneath continents, primarily composed of granite and sedimentary rock. Oceanic crust is the thinner, more dense, and younger type of crust located beneath oceans, primarily composed of basalt. The boundary between continental and oceanic crust is known as the continental-oceanic crust boundary.
A transform plate boundary does not create or destroy crust. Instead, adjacent plates slide horizontally past each other. This movement can cause earthquakes along the boundary without significantly changing the amount of crust.

Oceanic Crust
The East Pacific Rise is a divergent plate boundary where tectonic plates are moving apart. This boundary is associated with seafloor spreading and the creation of new oceanic crust.
