1. mineral : rock :: tree : forest

2.  pure, solid compound  non-biological processes (life does not assist in the process of formation)  very ordered molecular/atomic structure – usually results in a defined crystalline structure/pattern

6. Physical – does NOT change the chemical make-up of the substance –states of matter - liquid to gas –mixtures/solutions Chemical – does change the chemical make- up of a substance –chemical reaction takes place ** Most tests are physical property tests in an introductory course.
