1. Aim: How are igneous rocks formed?
Do Now: Take out new section of notes and label it rocks.

2. Igneous Rocks

3. Rocks that form when natural, molten (liquid)
rock-forming material cools into a solid

4. Liquid rock BENEATH Earth’s surface
is called magma

5. When magma comes out onto or above Earth’s surface it becomes LAVA

6. When magma solidifies beneath Earth’s solid
surface the rocks are called INTRUSIVE

7. When lava solidifies on or above Earth’s
solid surface the resulting rock is EXTRUSIVE

8. Formation
All igneous rocks are a result of the solidification of magma or lava.
Solidification can also be known as CRYSTALLIZATION

9. Crystal Size

10. Texture
Glassy, Fine, Coarse, Very Coarse
Non-vesicular vs Vesicular

11. Mineral Composition
