Name a mineral that is vital for human nutrition?
Minerals are naturally occurring elements or compounds found in the Earth's crust. They are essential for the formation of rocks and soils, and also form most of the Earth’s crust. Minerals are also essential for human nutrition and body functions.
Minerals - The Building Blocks of Earth's Structure
minerals: Naturally occurring elements or compounds found in the Earth's crust. rocks: Solid aggregate of minerals or mineral-like substances. soils: The upper layer of Earth's surface where plants grow.
Concepts:
There are more than 4,000 known minerals. Diamonds are made of carbon atoms that have been subjected to extreme heat and pressure. Gold is one of the few elements that can be found in its natural state. It does not need to be combined with other elements to exist.

are naturally occurring and are found everywhere in the geosphere from the tallest mountains to the seafloor. Minerals are composed of one or more elements.
What is a Mineral?
Solid Inorganic Definite Chemical composition Naturally occurring Made up of atoms (atoms in a solid are packed tightly together and vibrate in place. Solids have a definite shape and volume).
Characteristics of a Mineral
Made from Earth not in laboratories. 4,000 naturally occurring minerals but 30 are common. Ten of the rock-forming minerals are: Quartz, Feldspar, Olivine, Pyroxene, Amphibole, Mica, Calcite, and Halite.
Naturally Occurring
Some minerals are made up of one or more than one element. Minerals composed of two or more parts is a hematite. (Ex.: hematite Fe2O3) Native elements such as silver are composed of just one element. (Ex.: Ag)
Definite Composition
Minerals form crystal patterns The internal arrangement of atoms and ions determines the shape of a crystal.
Crystalline Form
All minerals are solid but not all solids are minerals Solid is matter tightly packed atoms or ions. It has a definite shape and volume. To be considered a mineral as solid must have a crystal form. Liquids and gases are not minerals because they are not solid.
Solid
Minerals are inorganic Crystallization is the formation of crystals. Occurs in different environments Can be caused by evaporation. Some minerals result as a form of organic processes.
Inorganic
Solid Inorganic Crystal Made atoms and ions Naturally occurring
What are the five main characteristics of a mineral?
Brain break: Create a surrealist painting using only objects found in or around your classroom. You must incorporate at least 5 objects in your painting, and you may use paint, pencils, or other materials to create the artwork. Be creative and think outside the box!
