Igneous rocks are made from molten lava. Then they become solid like a rock. There are two types of igneous rock. Intrusive and extrusive.Intrusive means the rock was made from inside the Earth by lava. Extrusive rocks are form by the on the Earth by hard molten lava. Sedimentary rocks are form by bodies of water within the Earths Crust . Metamorphic rocks are form by dead animals and plants together in a rock.
The two main features of sedimentary rocks are: They are formed into strata or layers. They consist of many palaentological evidences like fossils and coal.
Layers of rocks can curve downward due to tectonic forces. When two tectonic plates collide, the pressure and compression can cause the rocks to fold and bend. This folding can create downward curves known as synclines, where the youngest rocks are exposed in the center and older rocks are found on the sides.

Two layers of rocks (gaps in rocks filled with mortar) and earth in between the two layers of rocks.

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 two densest physical layers of the earth are the lithosphere and the asthenosphere.
