(of a rock) The tendency of a mineral to break along a plane - the mineral forms smooth planes.

Minerals are formed naturally by geological processes. A mineral is a homogeneous solid that can be made of single native element or more usually a compound. Minerals make up Earth's rocks and sands, and are an important component of soils. 5 characteristics required of all minerals

This hardened magma or lava is called igneous rock. Examples of igneous rocks include basalt and granite. Sedimentary Rocks - Sedimentary rocks are formed by years and years of sediment compacting together and becoming hard. Generally, something like a stream or river will carry lots of small pieces of rocks and minerals to a larger body of water.

Rocks on the Earth may be composed of hundreds of possible minerals but only 20 to 30 minerals are common in the majority of rocks. Minerals are made up of combinations of nearly a hundred different elements, yet only eight elements make up over 98% of the Earth's crust. Atoms represent the basic building blocks of the elements and the next ...

Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization. ...

A general difference between rocks and minerals is that minerals are chemical substances, while rocks are made from volcanoes and bodies of water.
