Seven characteristics commonly used to describe minerals are color, luster, hardness, streak, cleavage, fracture, and density. Color refers to the mineral's appearance, while luster describes how it reflects light. Hardness measures resistance to scratching, and streak is the color of the mineral's powder. Cleavage and fracture describe how a mineral breaks, and density indicates its mass relative to volume.

Two kinds of characteristics used to describe place are physical characteristics, such as landforms and climate, and human characteristics, such as population density and cultural aspects. These characteristics help differentiate one place from another and provide insights into its unique features.

The words "uneven" and "splintery" describe the fracture or cleavage of a mineral. Uneven fracture indicates a rough, irregular break, while splintery fracture refers to a break that results in thin, sharp fragments resembling splinters. These characteristics help identify the mineral's physical properties and behavior when subjected to stress.
Two distinguishing characteristics of a mineral are its crystalline structure and its hardness. Other field tests would include a streak test and possibly a test of specific gravity. Color can also be of some use.
