How do you identify minerals according to streak?
Minerals can be identified by their streak, which is the color of the mineral when it is broken down into a powder. To test a mineral's streak, a streak plate (usually made of unglazed porcelain) is used. The streak is usually compared to a streak color chart, which contains the colors of a variety of minerals. To test a mineral for its streak, take a small piece of the mineral and rub it on the streak plate. The resulting powder is then compared to the streak chart to identify the mineral. Streak is an important property of minerals because it is more reliable than the external color of the mineral. External color can be altered by impurities and oxidation, but the streak of a mineral does not change. Therefore, testing a mineral's streak is an effective way of identifying it.When identifying minerals according to streak, it is important to consider the following properties: Color - the color of the powder when rubbed on the streak plate. Luster - the shine of the powder when rubbed on the streak plate. Texture - the feel of the powder when rubbed on the streak plate. Opacity - the transparency of the powder when rubbed on the streak plate.By considering these properties when testing a mineral's streak, it is possible to identify the mineral accurately and quickly.
The most common mineral group is broken into the subgroups of ferromagnesium and nonferromagnesium?
its silicate
Weathering causes the mineral composition of rocks to change.?
Yes, weathering is the process by which rocks are broken down and their mineral composition can be altered. This can occur through physical weathering (mechanical breakdown of rocks) and chemical weathering (alteration of minerals through chemical reactions with water, oxygen, or other substances). Over time, this process can lead to the formation of new minerals and the breakdown of original mineral compositions in rocks.
Explains how subsoil becomes rich in minerals?
Subsoil becomes rich in minerals through the process of weathering, where rocks are broken down into smaller particles. This allows minerals to be released and accumulate in the subsoil layer over time. Additionally, the decomposition of organic matter can contribute to the mineral content in the subsoil as minerals are released from decaying plant material.
Classifications of minerals?
Minerals are classified into different categories based on their chemical composition, such as silicates, carbonates, sulfides, oxides, and sulfates. These categories are determined by the specific elements present in the mineral's structure. Each classification can further be broken down into subcategories based on the arrangement of atoms and other properties of the mineral.
What property is used to identify minerals uses the color of the mineral when it's broken up?
StreakColor of the mineral when it is powdered.Grind a small amount of a mineral into a powder on a porcelain streak plate and determine the color of the powder.
What property uses the color a mineral when it is broken up to identify it?
streak.
What is the property of a mineral that causes it to break with rough edges?
The property of a mineral that causes it to break with rough edges is called fracture. Fracture can occur in minerals that do not exhibit cleavage, resulting in irregular or jagged surfaces when the mineral is broken. This type of breakage is typically due to the mineral's atomic structure and how its bonds are oriented.
Why do minerals get processed?
It is all part of life minerals come and go so to start a new mineral you need an old broken down mineral

Step like cleavage is a property of what mineral?
Step-like cleavage is a property of the mineral mica. Mica minerals exhibit a planar arrangement of atoms that allow them to easily separate along flat surfaces, giving them a distinctive step-like appearance when broken or cleaved.
What mineral is broken down by acid?
Calcite is a mineral that can be broken down by acid, particularly by dilute hydrochloric acid. The acid reacts with the calcium carbonate in calcite, causing it to dissolve and release carbon dioxide gas. This reaction is commonly used to test and identify certain minerals in geology.
What is crystal cleavage?
It is a fault line, or fissure, along which it may be split.
How do minerals dissolve?
Minerals dissolve when they come into contact with a solvent such as water and the chemical bonds holding the mineral's atoms together are broken. This process involves the mineral's ions entering into the solution, leading to the mineral dissolving and dispersing into the solution. The ability of a mineral to dissolve depends on its chemical composition and the properties of the solvent.
What feature separates the mineral families from one another?
Minerals are classified according to the elements they contain. Other important features for classification purposes include the crystalline structure, hardness and cleavage of the mineral when broken.
The most common mineral group is broken into the subgroups of ferromagnesium and nonferromagnesium?
its silicate
Explain how to identify a mineral using color luster streak hardness cleavage fracture?
Luster is the light reflection a mineral has, which can be broken down into categories like metallic, silky, and dull. The luster dictates what type of mineral it is.
