Minerals Facts
Rocks are made of different types of minerals. Minerals are inorganic substances that exist naturally on Earth. Their formation begins with the melting and cooling of magma into a solid crystal. Then water containing dissolved minerals evaporates and leaves behind the mineral crystals.
Interesting Minerals Facts:
Scientists have stated that there are over 3,000 different types of minerals.
When two or more minerals combine together, they form a rock.
The most common mineral found on Earth is called quartz.
All minerals are inorganic because they are made of nonliving particles.
Minerals are always solid and have a distinctive geometric shape called a crystalline structure.
Each kind of mineral has the same set of chemicals in its make-up.
The mineral quartz always contains two oxygen atoms for every silicon atom.
Mineral crystals are so small that they can only be viewed under a microscope.
The cooling process of magma determines the size of the crystals that form in a mineral.
When magma cools at a slow rate, large mineral crystals are produced.
When magma cools at a fast rate, small mineral crystals are produced.
Olivine is a mineral often used to cast objects in aluminum.
The minerals our bodies need are different from the minerals found on Earth. Our body actually needs the elements found within the minerals.
The mineral feldspar covers about 60% of the Earth's crust and is used in the making of ceramics.
