  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?
