for #1-4, match the word with each definition:

1. metallic luster

a. dull, pearly, glassy

1. streak

b. how heavy a mineral sample feels

1. heft

c. looks like metal

1. nonmetallic luster

d. color of the mineral in its powdered form

1. fracture

e. flat and smooth

1. cleavage

f. rough and jagged
for #5-8, circle the correct answer:

1. which physical property refers to \scratchability\?

Explanation:

1. Matching Metallic Luster

• Explanation: Metallic Luster is the property of a mineral that makes it look like metal. So we match it with option C.
• Answer: C

2. Matching Streak

• Explanation: Streak is defined as the color of a mineral in its powdered form. So we match it with option D.
• Answer: D

3. Matching Heft

• Explanation: Heft refers to how heavy a mineral sample feels. So we match it with option B.
• Answer: B

4. Matching Nonmetallic Luster

• Explanation: Nonmetallic Luster includes appearances like dull, pearly, glassy. So we match it with option A.
• Answer: A

5. Matching Fracture

• Explanation: Fracture of a mineral is rough and jagged (unlike cleavage which is flat and smooth). So we match it with option F.
• Answer: F

6. Matching Cleavage

• Explanation: Cleavage of a mineral is flat and smooth (when it breaks along planes). So we match it with option E.
• Answer: E

7. Answering the "scratchability" question

• Explanation: The physical property that refers to "scratchability" is hardness. Hardness is a measure of how easily a mineral can be scratched or can scratch another substance. (Note: Since the options for this question are not fully visible in the provided image, but based on mineral properties, the answer is hardness. If there were options like "Hardness", "Luster", "Streak" etc., the correct option would be the one corresponding to hardness.)
• Answer: Hardness (assuming the options include hardness; if options were given, the specific option label with "Hardness" would be the answer)

Answer:

1. Matching Metallic Luster

• Explanation: Metallic Luster is the property of a mineral that makes it look like metal. So we match it with option C.
• Answer: C

2. Matching Streak

• Explanation: Streak is defined as the color of a mineral in its powdered form. So we match it with option D.
• Answer: D

3. Matching Heft

• Explanation: Heft refers to how heavy a mineral sample feels. So we match it with option B.
• Answer: B

4. Matching Nonmetallic Luster

• Explanation: Nonmetallic Luster includes appearances like dull, pearly, glassy. So we match it with option A.
• Answer: A

5. Matching Fracture

• Explanation: Fracture of a mineral is rough and jagged (unlike cleavage which is flat and smooth). So we match it with option F.
• Answer: F

6. Matching Cleavage

• Explanation: Cleavage of a mineral is flat and smooth (when it breaks along planes). So we match it with option E.
• Answer: E
