Crust and mantle
The Earth's crust consists of two main sub-layers: the continental crust and the oceanic crust. The continental crust is thicker, primarily composed of granitic rocks, and forms the continents. In contrast, the oceanic crust is thinner, predominantly made up of basaltic rocks, and underlies the ocean basins. These sub-layers differ in composition, thickness, and density.

The two layers of Earth that are made of rock are the crust and the mantle. The crust is the outermost layer, consisting of solid rock that forms the continents and ocean floors. Beneath the crust, the mantle is composed of semi-solid rock that flows slowly over geological time. Together, these layers play a crucial role in tectonic activity and the Earth's geology.
The Earth has three primary layers: the crust, the mantle, and the core. The crust is the thin outer layer made of solid rock, primarily composed of silicate minerals. Beneath it, the mantle is made of semi-solid silicate rocks that can flow slowly over time. At the center lies the core, which consists of a liquid outer core made of iron and nickel, and a solid inner core, also primarily composed of iron and nickel.

The crust and the mantle are the two layers of the Earth that are made predominantly of rocks. The crust is the outermost layer and is divided into continental and oceanic crust, while the mantle lies beneath the crust and is composed of solid rock.

Crust and mantle
The two layers of earth that are made up of liquids are the crust and the outer core. The crust is the surface of the earth which is where the oceans are. The outer core is made up of iron and is the creator of the earths magnetic field.

The other two layers of the Earth are the mantle and the core. The mantle is primarily composed of silicate minerals, while the core is mostly made of iron and nickel.
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
