Interesting Facts. Did you know that most of the Earth's crust is made of metamorphic rock? Well it's true! Even though the rock gets really, really hot and is under a whole heap of pressure it doesn't melt. Wow, that's one strong rock. If it did melt, that would mean that either igneous or sedimentary rocks …

The formation of rocks results in three general types of rock formations. Igneous rocks form from magma (intrusive igneous rocks) or lava (extrusive igneous rocks). Sedimentary rocks form from sediments worn away from other rocks. Metamorphic rocks occur when heat and/or pressure impact other rocks.

Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas.

Sedimentary rocks are formed at the surface of the Earth, either in water or on land. They are layered accumulations of sediments-fragments of rocks, minerals, or animal or plant material. Temperatures and pressures are low at the Earth's surface, and sedimentary rocks show this fact by their appearance and the minerals they contain.
