  1. II. Section 2 Properties of Magma

  2. A. Physical and ChemicalProperties • Element- substance thatcannotbebroken down intoother substances • Compound- a substance thatis made of two or more elements • Physicalproperty-canbeobserved and measuredwithoutchanging the composition of the substance

  3. 5. Density, hardness, melting point, boiling point, magnetism 6. ChemicalProperties-propertythatproduces a change in the composition of matter 7. Burnablility, reactionwithother substances

  4. B. What Is Viscosity? • The resistance of a liquid to flow • The greater the viscosity, the sloweritflows, the lower the fasteritflows • Greater friction, greaterviscosity

  5. C. Viscosity of Magma • Silica-oxygen, silicon • More silica the more viscosity, light color • lesssilica, lessviscosity, darkcolor

  6. 4. Temperature- Viscosity increases as temperature decreases (Honey) 5. Pahoehoe- fast moving, hot lava, low viscosity 6. Aa- higher viscosity, slower, cooler
