Basic concepts of chemistry are essential to understanding the physical and chemical properties of earth materials (minerals, rocks, organic matter, etc.).
The chemical characteristics of earth materials are reflect the environments how and where they are formed, they also determine their potential fate when exposed to chemical changes.
Common examples of elements are iron, copper, silver, gold, hydrogen, carbon, nitrogen, and oxygen.The CPARS applications are designed for UNCLASSIFIED use only.Classified information is not to be entered into these applications.This section presents many basic concepts that are universal to all physical sciences.1. A mineral is a naturally occurring, inorganic (never living) solid with a definite internal arrangement of atoms (crystal structure) and a chemical formula that only varies over a limited range that does not alter the crystal structure.What are "rocks" and "minerals" - explain the differences. Describe essential concepts of chemistry related to earth materials. What is the chemical and mineral composition of the Earth's crust? List some common silicate and nonsilicate minerals. Describe and illustrate the "rock cycle" as it relates to processes and products. Describe basic geologic principles for interpreting landscape forming processes. On Earth, more than 4,000 minerals have been identified, however, of those fewer than 2 dozen are common minerals in Earth's physical environment (Figure 1-1 shows common rock-forming minerals).

Rapid rock formation can be seen happening such as lava cooling from a volcanic eruption in places like Hawaii or Iceland.
