it usually makes an earthquake.
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
When a piece of Earth's crust is subducted, it sinks into the mantle beneath another tectonic plate. This process occurs at convergent plate boundaries, where an oceanic plate often subducts beneath a continental plate due to its higher density. As the subducting plate descends, it can lead to the formation of deep ocean trenches, volcanic activity, and earthquakes. The intense heat and pressure can also cause the subducted material to melt and contribute to magma formation, resulting in volcanic eruptions.
When oceanic crust meets another piece of oceanic crust, one of the plates is typically subducted beneath the other due to differences in density. This subduction can lead to the formation of deep ocean trenches and volcanic island arcs. The intense pressure and heat at the subduction zone can also result in geological activity, including earthquakes and the creation of magma that may rise to form volcanic islands. Overall, this interaction plays a crucial role in the dynamics of plate tectonics.
Where oceanic crust is subducted under continental crust, a trench, volcanic arc, and earthquakes are likely to form. The subduction of the dense oceanic plate causes it to sink beneath the less dense continental plate, leading to the creation of these geological features due to the intense heat and pressure generated in the process.
When a plate carrying continental crust converges with a plate carrying oceanic crust, the denser oceanic plate is typically subducted beneath the less dense continental plate. This can lead to the formation of volcanic arcs and deep ocean trenches.

Oceanic crust gets subducted into the mantle.
The crust is compressed into mountains (if it is continental crust) or subducted back into the mantle if it is oceanic crust.
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.

When new crust is made, like at a spreading center, old crust must be destroyed, like at a subduction zone, where it is brought back into the inner earth and melted and recycled through.
