Would the hardness of a mineral affects its performance in the streak test why or why not?
No. Streak color is distinct of mineral hardness. They are separate properties.
What are three types of mineral luster?
Glassy luster, Metallic luster and Waxy luster.
What are two pieces of criteria for identifying a mineral?
Two distinguishing characteristics of a mineral are its crystalline structure and its hardness. Other field tests would include a streak test and possibly a test of specific gravity. Color can also be of some use.
What is Cobalts mineral streak color?
Yes. Its Mohs hardness is in the range of 5, and minerals (or metals, as is the case here) will streak up to a hardness of about 7. For a quick review of what streak is and how it originated, use the link to the Wikipedia article.
What is the difference between a minerals hardness and streak?
A minerals hardness is the ability to scratch or be scratched by other minerals and streak is the colored powder of a mineral that comes off when being scratched.
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 does the term property of a mineral mean?
Property would refer to any identifier of the mineral, such as chemistry, hardness, luster, specific gravity, streak, melting point, etc..
What are the the tests scientists use to identify minerals?
Hardness test based on the Mohs Scale of relative mineral hardness, specific gravity, streak test for mineral color, classification of mineral crystal system, chemical analysis.
What are the 6 properties used to identify mineral?
In a hand sample/specimen you can the properties used to identify minerals are luster, diaphaneity, color, streak, luminescence, play of colors, crystal shape, tenacity, cleavage, hardness, specific gravity and density, magnetism, electrical properties, reaction to acid.
What are 6 ways to identify a mineral?
Lustre Colour Cleavage Hardness Streak Crystal Habit Specific Gravity Magnetism Effervescence Double Refraction Taste Feel

What is the difference between streak and specific gravity?
Streak: The powder mark left by a mineral when it is rubbed against a harder object. Specific Gravity: The exact weight of an object.
What are three types of mineral luster?
Glassy luster, Metallic luster and Waxy luster.
What is the definition for the hardness of a mineral?
Hardness - measure of how easily a mineral is scratched.
What is rock streak?
Streak is a method used to help identify minerals. A mineral can have very similar characteristics such as luster, colour, hardness, specific gravity ect, but even minerals with very similar characteristics including colour can have different streaks...which is the 'colour' the mineral makes on a scratch plate when drawn accross it in a stroke..thus creating the streak.
What is the difference between streak and hardness?
A minerals hardness is its relative ability to scratch or be scratched by other minerals. Diamond, for instance, can scratch all other minerals because of its hardness. Streak is the color of the mineral when powdered. This is usually accomplished by the streak test (swiping the mineral across an unglazed porcelain surface) which reveals a mineral's streak color, which may differ from the color of the specimen being tested.
