Oceanic crust is more dense.
Deep sea trenches, Mountain ranges, Volcanoes, and Earthquakes.
continental slope
The largest layer of Earth's surface is the crust, which is divided into oceanic and continental crust. The continental crust is thicker and less dense than the oceanic crust, covering about 40% of the Earth's surface.
The three most common elements in Earth's continental crust are oxygen, silicon, and aluminum. In the oceanic crust, the predominant elements are oxygen, silicon, and magnesium. While oxygen and silicon are abundant in both types of crust, aluminum is more prevalent in the continental crust, whereas magnesium is more common in the oceanic crust.
The crust is the least dense portion of the solid Earth because it is the thinnest layer.

oceanic crust
Oceanic crust, new oceanic crust is produced by seafloor spreading.
a portion is a small amount of it
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.

one and a half miles thick
Earth's oceanic crust is thinner, denser, and younger than Earth's continental crust. It is primarily composed of basaltic rock, whereas continental crust is made up of less dense granitic rock. Oceanic crust is constantly being formed at mid-ocean ridges and destroyed at subduction zones.
