  2. Igneous Rocks 8/19 What is an igneous rock? What is crystallization What determines the type of igneous rock will form? What is the difference between fine and coarse grained? What is the difference between extrusive and intrusive ? What are some examples of igneous rock?

  4. 2. Crystallization is when magma or lava hardens and become s crystal

  5. 3. The type of igneous rock formed is determined by composition and how fast or slow lava or magma cools

  6. 4. Fine grained-lava cools quickly with small crystals Coarse grained-magma cools slowly with large crystals

  7. 5. Extrusive-forms on Earth’s surface from lav a • Intrusive-forms inside Earth’s from magma
