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.

Ductility is a physical property.
A physical property of a material is a property that can be measured or observed without changing the composition of the material.
In this case ductility is a physical property. It is defined as the property of a material associated with the ability to be drawn or stretched into a wire without breaking. The chemical identity of the material is not affected, that is it does not change.
Example of ductile materials include gold, silver, copper, erbium, terbium and samarium.
Other examples of physical properties are:
1. Solubility
2. Melting point.
3. Boiling point.
4. Color
5. Density.
Well, there is only one realistic answer. Option One is when you take the DNA of two different people or creatures and combine them into one organism. Cloning wouldn't prove anything here, "hybridization" is weird - but it doesn't have anything to do with the situation. So only only remaining option is DNA Profiling - also known as DNA Mapping, which shows the DNA structure and order that can be seen the same way in siblings (slightly different of course but it is still the right answer).
