What are four characteristics of mineral which can be used to identify it?
Color, streak color, hardness, cleavage, and chemical.
Can you identify a mineral by its physical properties?
Color, reflectivity, purity. Just to name a few.
What is the eight ways to identify a mineral?
By the mineral color, streak color, luster, hardness, the property of the mineral, if it's fracture or cleavage and it's specific gravity. Those are just basic, so there's many other ways to ID a 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.
How do you identify minerals with your naked eyes?
by simply testing the streak of the mineral. all minerals have a different streak take a streak plate and scrape the rock down it in a straight line and the color should tell you what mineral it is :) that's the best way.

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.

Does the color of a minerals streak depend on the color of the mineral?
No. It can vary from the visible color of the mineral and, since visible color of them ineral is not a reliable indicator of type, it is important to learn to use streak, (along with other factors), to correctly identify a mineral.
