The color of a Mineral in powdered form is called
The color of a Mineral in powdered form is called
Show Hint
Streak is the color of a mineral in powdered form and is often more reliable than surface color for mineral identification.

- Streak
- Texture
- Shade

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
In mineralogy, minerals are identified by several physical properties such as color, luster, hardness, cleavage, fracture, and streak.
Step 1: The ordinary color of a mineral is the color seen on the mineral surface.
Step 2: Sometimes the surface color of a mineral may vary due to impurities, weathering, or surface oxidation.
Step 3: Therefore, for better identification, the mineral is rubbed on an unglazed porcelain plate.
Step 4: The color of the powder left behind by the mineral is called its streak. \[ \text{Color of mineral in powdered form}=\text{Streak} \]
Step 5: Luster means the way a mineral reflects light from its surface, texture means the surface feel or arrangement, and shade is simply a variation of color. Therefore, the correct answer is: \[ \boxed{\text{Streak}} \]
