Which term describes the characteristic crystal shape of a specific mineral?

• A. Habit
• B. Half-life
• C. Igneous
• D. Indicator minerals

Answer: (A)

Habit is the term used to describe the characteristic crystal shape a mineral tends to form under given growth conditions. It captures the overall external form of crystals, such as euhedral (well-formed), prismatic, tabular, cubic, or fibrous shapes, and reflects how the mineral’s crystals grew in space and time. The other terms aren’t describing crystal shape: half-life is a radiometric concept related to how quickly a radioactive element decays, Igneous refers to rocks formed from cooling magma or lava, and indicator minerals are minerals that signal certain geological conditions or ore deposits rather than describing their crystal form. So, the term that best fits the idea of a mineral’s characteristic crystal shape is habit.
