hardness

A mineral’s is its resistance to being scratched. Like a mineral’s cleavage, a mineral’s hardness is determined by its crystal structure and the strength of the bonds between its atoms. Harder minerals have stronger bonds. A scale known as the Mohs scale is often used to describe a mineral’s hardness.

Cleavage and Fracture Since some bonds are weaker than other bonds, each type of mineral is likely to break where the bonds between the atoms are weaker. For that reason, minerals break apart in characteristic ways. Cleavage is the tendency of a mineral to break along certain planes to make smooth surfaces.

A mineral has to be naturally occurring, inorganic, solid, have a crystal structure, and have a definite chemical composition.

Minerals are also important for making enzymes and hormones. There are two kinds of minerals: macrominerals and trace minerals.

A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes. Examples include quartz, feldspar minerals, calcite, sulfur and the clay minerals such as kaolinite and smectite.

Minerals are classified into two types: Metallic and non-metallic. Metallic Minerals: They are further sub-divided into ferrous and non-ferrous. Non-ferrous minerals: They contain metals other than iron. Examples include gold, silver, copper, lead, bauxite, tin and magnesium.

Mineral like copper is used in electrical equipments as it is good electrical conductor. Clay is used to make cement etc which helps in constructing roads. Fibreglass, cleaning agents are made by borax.

Answer:1. For minerals to form through natural processes, the correct elements must be present in the right amounts. The physical and chemical conditions, such as temperature, pressure, and pH, must be favorable. In addition, there must be enough time for the atoms to become ordered.

Minerals occur in different types of rocks. Some are found in igneous rocks, some in metamorphic rocks while others occur in sedimentary rocks. Generally, metallic minerals are found in igneous and metamorphic rock formations that form large plateaus.

mineral are usually found beneath the earth.

The 5 Most Important Minerals

1. Iron. Yes, I’m starting with the most obvious.
2. Calcium. We all know calcium is necessary for strong bones, and it’s especially important for kids.
3. Magnesium. Magnesium is crucial for both bone health and energy.
4. Zinc. Zinc has a few key jobs.
5. Potassium.

Calcium is the most abundant mineral in the human body, making up 1.5 to 2% of the total body weight. Approximately 1,200 g of calcium are present in the body of an adult human; more than 99% of that amount is found in bones.
