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 rocks formed?  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?
