Unit 5 - Geology - Minerals & Rocks
Regents Standards:
3.1a. Minerals have physical properties determined by their chemical composition and crystal structure.
• Minerals can be identified by well-defined physical and chemical properties
such as:
• cleavage
• fracture
• color
• density
• hardness
• streak
• luster
• crystal shape
• reaction with acid.
3.1b. Minerals are formed inorganically by the process of crystallization as a result of specific environmental conditions.
These include:
• cooling and solidification of magma
• precipitation from water caused by such processes as evaporation
• chemical reactions
• temperature changes
• rearrangement of atoms in existing minerals subjected to conditions of high temperature and pressure.
3.1c. Rocks are usually composed of one or more minerals.
Rocks are classified by their:
• origin
• mineral content
• texture.
Conditions that existed when a rock formed can be inferred from the rock's mineral content and texture.
