All minerals exhibit cleavage.

A mineral can be composed entirely of one element.

Moh's hardness scale is a relative measure of which physical property of minerals?

A cubic centimeter of quartz, olivine, and gold weighs 2.5, 3.0, and 19.8 grams respectively. This indicates that ________.

A compound is a stable chemical substance composed of two or more ________.

Overall, the physical properties of minerals provide a reliable means to identify common minerals. However, certain properties can exhibit a range of characteristics or values making them less useful for identification purposes. Choose three physical properties that might vary considerably between samples of the same mineral and explain why such variability might exist.
