Minerals vs. Rocks Minerals - inorganic solid material that rocks are made of Characteristics used to identify minerals: Hardness, Luster, Streak Rock - solid, inorganic material made of one or more minerals Types of Rocks: Igneous, Sedimentary, Metamorphic

Igneous Rock “Fire Rock” Formation: rock made when lava or magma cools and hardens Types of Igneous Rocks: Extrusive and Intrusive Extrusive igneous rock - igneous rock formed above ground, no or small crystals form Examples: Pumice, Obsidian Intrusive igneous rock - igneous rock formed underground, large crystals form Examples: Granite, Gabbro Analogy: An igneous rock is like a Jolly Rancher because…

Sedimentary Rock Formation: made from sediments, pieces of broken rock and minerals, deposited in layers Types of Sedimentary Rocks: Detrital, Organic and Chemical Examples: Coal , Sandstone, Conglomerate, Shale Analogy : A sedimentary rock is like a layered cookie bar because…

Metamorphic Rock Formation: formed when igneous or sedimentary rock is changed by heat and pressure Types of Igneous Rocks: Foliated and Nonfoliated foliated rock- metamorphic rock with visible layers of minerals Examples: Slate (Shale becomes Slate), Gneiss (Granite becomes Gneiss) nonfoliated rock- metamorphic rock without visible layers of minerals Examples: Marble (Limestone becomes Marble) Analogy: A metamorphic rock is like pot roast left overs that turn into stew because…
