What else can I help you with?
What name is given to the dust that is left on a surface after a mineral has been scraped across it?
The dust left on a surface after a mineral is scraped across it is called streak.
What happens to the surface of a mineral if the acid test is positive?
If the acid test is positive for a mineral, the surface of the mineral may show signs of fizzing or bubbling due to a chemical reaction between the acid and the mineral. This reaction indicates that the mineral contains carbonate minerals like calcite or dolomite, which are reactive to acid.
The color of a minerals powder is its what?
The color of a mineral's powder is its streak. This is the color of the powdered form of the mineral when it is scraped against a hard surface. Streak is a more reliable indicator of a mineral's identity than its exterior color.
What is the color of the powder that a mineral leaves went is scratched across a special plate?
The color of the powder left by a mineral when scratched across a special plate is called the streak color. This color may differ from the actual color of the mineral itself and is a helpful characteristic in mineral identification.
When a mineral is rubbed on a rough surface it leaves a streak or luster?
When a mineral is rubbed on a rough surface, it leaves a streak due to the color of the powdered mineral. The luster of a mineral refers to the way its surface reflects light, which can be metallic, glassy, pearly, dull, or oily in appearance.
What name is given to the dust that is left on a surface after a mineral has been scraped across it?
The dust left on a surface after a mineral is scraped across it is called streak.
What refers to the color of powder scraped off a mineral when it is rubbed against a hard rough surface?
The color of the powder left on the rough surface by a mineral is called its streak. The streak plate is a hard surface that helps to determine the different shades and characteristics of the minerals that is rubbed on it.
Does A minerals ability to reflect light refer to streak?
No, a mineral's ability to reflect light does not refer to streak. Streak is the color of the powder left by a mineral when it is scraped across a rough surface. The ability of a mineral to reflect light is usually related to its luster, which describes how light interacts with the mineral's surface.
What is a mineral silicate?
A silicate mineral is a mineral that contains both silica and oxygen. They make up about 95 percent of the Earth's surface.
How are streak and luster alike?
Both streak and luster are properties used to identify minerals. Streak is the color of the powder left behind when a mineral is scraped against a harder surface, while luster describes how light is reflected off the surface of a mineral. Both properties can provide clues about the identity and composition of a mineral.
What happens to the surface of a mineral if the acid test is positive?
If the acid test is positive for a mineral, the surface of the mineral may show signs of fizzing or bubbling due to a chemical reaction between the acid and the mineral. This reaction indicates that the mineral contains carbonate minerals like calcite or dolomite, which are reactive to acid.
The color of a minerals powder is its what?

What is the streak of tanzanite?
Tanzanite has a streak that is typically a light blue to violet color. Streak refers to the color of the powder produced when a mineral is scraped across a hard surface, such as a porcelain plate. This characteristic can be useful in identifying the mineral, as the streak color may differ from the color of the mineral itself. Tanzanite's streak helps to confirm its identity in mineralogy.
What is the color of the powder that a mineral leaves went is scratched across a special plate?
The color of the powder left by a mineral when scratched across a special plate is called the streak color. This color may differ from the actual color of the mineral itself and is a helpful characteristic in mineral identification.
What is a mineral's streak?
The color the mineral makes on a hard surface

What is a dust strom?
A body turbulent air that contains within it an appreciable amount of fine mineral based material that has been whipped up from the Earth's surface.
