Would the hardness of a mineral affects its performance in the streak test why or why not?
No, the hardness of a mineral does not affect its performance in the streak test. The streak test measures the color of the powdered form of a mineral when it is scratched against a streak plate, regardless of the mineral's hardness.
What color line when a mineral is rubbed on a surface?
The color of the line left when a mineral is rubbed on a surface is called the streak color. This color may be different from the color of the mineral itself due to factors such as impurities or the mineral's composition. Streak testing is useful in identifying minerals as it can help distinguish between similar-looking minerals based on their streak colors.
What would you observe in a streak test?
In a streak test, you would observe the color of the powdered mineral after it has been scraped against a porcelain plate. The color of the streak left behind can sometimes be different from the color of the mineral itself, which can be helpful in identifying the mineral.
How do you know a mineral's streak?
The streak of a mineral can distinguish between two samples that have the same color. The streak is often a different color. To test streak, use a streak plate. This is a piece of unglazed porcelain, like the back side of a tile.
What materials do you need to test the streak?
To test the streak of a mineral, you will need a streak plate (unglazed porcelain), the mineral sample, and a way to scratch the mineral against the streak plate to observe the color of the powder residue left behind.
What color streak does garnet leave?

Harder minerals will not streak, but this can also be used as a tool for identifying the mineral, if you are familiar with the hardness scale.
Was is sulfur's streak?

A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
