  4. Question 3 • What is the chemical composition of olivine?

  5. Question 4 • What controls a minerals property?

  6. Answers • What is a minerals? • Solid, inorganic, naturally occurring • Nonmetallic, flexible in thin sheets • Biotite • What is the chemical composition of olivine • (Fe,Mg)2 SiO4 • What controls a minerals property? • IAOA

  7. Rocks & Minerals The Building Blocks of society

  8. Igneous Rocks Made from Magma and Lava

  9. Igneous rocks • How are igneous rocks formed? • What do igneous rocks look like? • What do the characteristics tell us about the rock? • What are igneous rocks used for? • How do you use page 6 of the ESRT for Igneous rocks?

  10. How are igneous rocksformed? • Extrusive or volcanic - lava on the earth’s surface • Intrusive or plutonic - inside the earth’s crust, magma chambers

  11. What do igneous rocks look like? • Vesicular = gas bubbles (extrusive) Or • Nonvesicular = no gas bubbles

  12. What do igneous rocks look like? • Felsic light in color and density, rich in aluminum (continental crust) or • Mafic dark in color and high in density, rich in iron and magnesium (ocean crust)

  13. What do igneous rocks look like? • Texture can be glassy, fine grained, coarse grained, or very coarse grained

  14. What do the characteristics tell us about the rock? • Cooled slowly in the crust = large minerals • Cooled rapidly on the surface = no or very small minerals • Vesicular = very gaseous lava flow

  15. What are igneous rocks used for?

  16. How to use esrt page 6 - Igneous Rocks?
