Minerals A mineral is a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition

Rocks are made up of minerals

Coarse Grain large crystals Rocks have grain sizes Coarse Grain large crystals Fine Grain small crystals

Igneous rocks form from magma or lava

Magma = inside the Earth Lava = outside the Earth

Extrusive Rocks Lava that cooled outside the earth (on the surface, cooled faster) Fine grain, smaller crystals

Intrusive Rocks Magma that cooled inside the earth (cooled slower) Coarse grain, larger crystals

Metamorphic Rocks Metamorphic rocks form from heat and pressure deep beneath earths surface Metamorphic rocks can form out of igneous, sedimentary, or other metamorphic rocks

Sedimentary Rocks Sedimentary rocks form from particles deposited by water and wind that have compacted and cemented together

Fossils are ONLY found in sedimentary rocks

All rocks on Earth were a different type of rock at one point in time The Rock Cycle Rocks are always changing through Earths processes. We illustrate how rocks change through the Rock Cycle. The rock cycle can follow many different pathways. All rocks on Earth were a different type of rock at one point in time
