Oceanic crust or a less solid piece of oceanic crust will subduct beneath continental crust. Earthquakes occur when the oceanic plate subducts into a trench. Volcanoes are created by the melting of mantle material.
<h3>What does oceanic crust mean?</h3>
The outermost part of the Earth's lithosphere, known as oceanic crust, is created at spreading centres on oceanic ridges that are found at divergent plate boundaries and is found beneath the oceans. The oceanic crust is roughly 4 miles (6 km) thick. Even without the sediment on top, it is made up of many layers.
<h3>What is a characteristic of oceanic crust?</h3>
Compared to continental crust, oceanic crust is both thinner and denser. This is because to the oceans' weight, which has compacted it beneath it. It is also much more recent than continental crust, typically existing within the last 200 million years.
