What type of crust

There are two main types of Earth's crust:

• Continental crust is the layer of igneous, sedimentary, and metamorphic rocks that forms the continents and the areas of shallow seabed close to their shores. It is generally thicker (30-70 km), less dense, and older than oceanic crust.
• Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate. It is thinner (5-10 km), denser, and younger than continental crust, primarily composed of basalt and gabbro.
