Stone is another common term used to describe rock. Figure 2-2 shows how minerals can be combined to form different kinds of rocks that form under different environmental conditions.

This also applies to rocks, minerals, and derivative materials (such as sediments and soil).It is conceptually important that each rock has an origin in concepts of place, time, and physical and chemical conditions. These changes may be rapid (such as a volcanic explosion) or gradual, taking place over millions or billions of years, and involving movement over great distances, both at the surface or to deep within the Earth's crust below us.Trying to explain the what, how, and when of a rock's journey is fundamental to explaining why rocks are significant to resolving questions about our Earth's history and conditions within the physical environments where we live.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).
