Correct Answer
B. CleavageExplanation
Cleavage is the tendency of a mineral to break along flat, smooth surfaces. This means that when a mineral is subjected to stress, it will break along specific planes of weakness, resulting in flat and smooth surfaces. This is different from fracture, which is the tendency of a mineral to break irregularly and not along specific planes. Luster refers to the appearance of a mineral's surface in terms of its shine or reflectivity, while hardness refers to a mineral's resistance to scratching.Rate this question:
