Why do field geologist usually carry a small plate of unglazed porcelain what is it used to test?
it is used to test streak, for rocks and minerals
Which minerals on the Mohs scale will not leave a streak on the streak plate?
Diamond, corundum, and hematite are three minerals on the Mohs hardness scale that will not leave a streak on the streak plate because they are harder than the streak plate itself.
Which physical property would be best to use to distinguish hematite from the other mineral?
One physical property that can be used to distinguish hematite from other minerals is its streak color. Hematite typically leaves a reddish-brown streak when scratched against an unglazed porcelain plate. This can help differentiate it from other minerals that may have different streak colors.
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 is a scientific sentence for streak?
A streak is a line or band of a different color or texture from its surroundings, often used to describe patterns seen in minerals or rocks. It can be used in mineral identification to help differentiate one mineral from another based on its unique streak color.
