Hello, and welcome back to my blog that will open your eyes up with new opportunities and new knowledge. Today, we were learning about minerals and we watched a power point! Here are some things that you might find interesting.....
What is a mineral?
The exact definition is; A mineral is a naturally occurring solid that can form by inorganic processes and that has a crystal structure and a definite chemical composition. You can't really say it in any other way because those are the five things that a mineral must have if you want to classify it as a mineral!
What are the five things a mineral needs to have to be a mineral?:
- Solid - Minerals are always solid with definite volume and shape
- Naturally Occurring - Natural processes, can form when magma cools, from the remain of ancient plants, etc.
- Inorganic Processes - Every mineral must be able to from from material that were not part of a living thing.
- Fixed Chemical Composition - A mineral always contains certain elements in definite proportions.
- Crystal Structure - Particles of a mineral line up in a pattern that repeats over and over again. Crystals have flat sides that meet at sharp edges and corners.
