Arrange the following minerals in decreasing order of their hardness as per Mohs scale.
A. Orthoclase
B. Calcite
C. Corundum
D. Fluorite
A. Orthoclase
B. Calcite
C. Corundum
D. Fluorite
Show Hint
- A, B, C, D
- A, C, B, D
- C, A, D, B
- C, B, D, A
The Correct Option is C
Solution and Explanation
Step 1: Recall the hardness values of the given minerals on the Mohs scale. - Corundum (C): 9 - Orthoclase (A): 6 - Fluorite (D): 4 - Calcite (B): 3
Step 2: Arrange these minerals in decreasing order of hardness. The order from hardest to softest is: 1. Corundum (9) 2. Orthoclase (6) 3. Fluorite (4) 4. Calcite (3)
Step 3: Write the final sequence using the letters. The sequence is C, A, D, B.
