Three Main Kinds of Rocks

The Rock Cycle

• Relates rock creation to tectonic processes,
  atmospheric processes, and oceanic processes
• Any rock type can be created from any other rock
  type
• A cycle the process can go around many times,
  recycling the elements or minerals that make up
  the rock

Key Concepts

• The Rock Cycle is a concept that recognizes that
  elements and minerals making up rocks can be
  re-cycled to create new kinds of rocks
• Agents of re-cycling include
• Erosion
• Burial
• Heating
• Melting
• Deposition
• Fluid transport chemical reactions
• The Tectonic setting governs which agents operate
• Be prepared to describe a tectonic setting and
  how the rock cycle works in that context!
