The tendency of a mineral to break along smooth planes is called
cleavage
fracture
rupture
breakage
refraction
Solution
The answer is the first one: cleavage.
Explanation for each option:
Cleavage: This is the correct answer. Cleavage refers to the tendency of a mineral to break along smooth, flat planes where atomic bonds are weaker.
Fracture: This is incorrect. Fracture describes how a mineral breaks when it does not follow any natural planes of separation, resulting in irregular or curved surfaces.
Rupture: This is incorrect. Rupture is a general term for breaking or bursting and is not specific to the characteristic way minerals break.
Breakage: This is incorrect. Breakage is a non-specific term and does not refer to the characteristic way minerals break along specific planes.
Refraction: This is incorrect. Refraction refers to the bending of light as it passes through a substance, not the breaking of minerals.
Summary:
The tendency of a mineral to break along smooth planes is called cleavage.
