The color of a minerals powder is called ____________ by geologists.
- A.
Luster
- B.
Fracture
- C.
Cleavage
- D.
Streak
- E.
Density
Correct Answer
D. StreakExplanation
The color of a mineral's powder is called "streak" by geologists. Streak refers to the color of the powdered form of a mineral when it is scraped across a streak plate. This characteristic helps geologists identify minerals, as the streak color can sometimes be different from the color of the mineral itself.Rate this question:

The term(s) used by geologists to describe how a mineral breaks apart under pressure is called?
- A.
Fracture
- B.
Cleavage
- C.
Both A & B
- D.
Neither A nor B
Correct Answer
C. Both A & BExplanation
Both fracture and cleavage are terms used by geologists to describe how a mineral breaks apart under pressure. Fracture refers to the way a mineral breaks irregularly, resulting in rough and uneven surfaces. Cleavage, on the other hand, describes the tendency of a mineral to break along flat, smooth planes. So, both fracture and cleavage are important concepts in understanding the behavior of minerals under pressure.Rate this question:

Each mineral has a characteristic ____________, which is defined as its mass in grams compared to (or divided by) its volume in milliliters.
- A.
Heft
- B.
Density
- C.
Permeability
- D.
None of the above
Correct Answer
B. DensityExplanation
Density is the correct answer because it is defined as the mass of a mineral divided by its volume. It is a characteristic property of minerals that helps to identify and distinguish them from each other. Heft refers to the weight or perceived weight of an object, while permeability refers to the ability of a substance to allow fluids or gases to pass through it. None of the above options accurately describe the characteristic of minerals being discussed.Rate this question:
