background image Chapter 29: Earth Materials   The Rock Cycle  Igneous: type of rock produced when melted material (like magma) solidifies or cools 
Sedimentary: type of rock created from sediments weathered from other pre-existing rocks 
Metamorphic: type of rock produced where pre-existing rocks are crystallized  
  
*All three types of rocks can transform into the other types --> the rock cycle * 
  
Minerals: Building Blocks of Rocks  •  Minerals: created from elements' extended bond sets; building block of rocks  •  Properties:   Naturally occurring   Inorganic solid  Fixed or narrowly limited chemical composition  Definite internal crystal structure (a regular molecular structure)  Exists within a defined range of pressure, temp, and moisture      Igneous Rocks  •  Mantle is a mix of solids and liquids (magma) because of its range of melting temperature and 
pressure 
•  Less dense magma rises above the crust/mantle and cools to form rocks  If it solidifies beneath the crust --> plutonic rocks  If it solidifies above the crust --> volcanic rocks     Soil and Sedimentary Rocks  •  Physical weathering (breaking rocks down through freezing and thawing) create talus  •  Chemical weathering (like acidic reactions) dissolve rocks and minerals to create more stable 
minerals  
Stalagmites and stalactites      Metaphoric Rocks  •  Foliation: structural or chemical arrangement into layers of materials in a rock
