a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. 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

What is difference between regression testing and retesting?
A regression test is a test where a previously known bug is tested for after a change. A retest is simply repeating a test.
Difference between quantitative and qualitative test?

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 kinds of tests can you do to figure out the difference between diamonds and calcite?
The tests you can do is the streak test, the luster test,the finger nail test(which is scratching it ti see if its hard or not).
How is the streak test different than the scratch test?
because the lava inside the magma moves more and more that it just exlodes
What isn't a streak test used to help identify every mineral?
A streak test is not used to identify minerals with a hardness greater than 7 on the Mohs scale, as these minerals can scratch the streak plate. Additionally, streak tests may not be effective for identifying minerals that have a streak color similar to the streak plate itself.
What does a mineral and streak tell you and how do you test for it?
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.

Does the streak test work with all minerals?
No it does not work with all minerals. For if you did not know streak plates have a hardness of 7 (maybe a little lower or higher) on the Mohs scale. Some minerals are harder than 7 though. If they are harder they will not work with the streak test. some examples are Diamond, topaz, and corundum.
What test would you perform to distinguish hematite form copper how would you carry out this test?
You can perform a streak test to distinguish between hematite and copper. Copper will leave a reddish-brown streak, while hematite will leave a reddish-brown to dark red streak. To carry out the test, you would take a streak plate or unglazed porcelain and rub the sample against it to observe the color of the streak left behind.

What is the difference between streak and hardness?
Streak refers to the color of a mineral when it is crushed to a powder, while hardness is a measure of a mineral's resistance to scratching or abrasion. Streak is determined by rubbing a mineral against a rough surface, while hardness is measured using the Mohs scale ranging from 1 (softest) to 10 (hardest).
Why could the streak of corundum be difficult to determine?
Corundum has a streak that is typically colorless, making it difficult to determine on a streak plate. The hardness of corundum (9 on the Mohs scale) can also affect the accuracy of the streak test, as it can scratch the streak plate instead of leaving a distinct streak.
