At a divergent plate boundary, oceanic crust is formed.
The correct answer is oceanic crust. At a divergent plate boundary, where two tectonic plates are moving apart, magma rises up from the mantle and creates new crust. This newly formed crust is referred to as oceanic crust. It consists mainly of basalt, a type of volcanic rock. Over time, as the magma cools and solidifies, it forms a continuous crustal structure along the divergent plate boundary. The process of creating oceanic crust is known as seafloor spreading and is responsible for the formation of mid-ocean ridges.
