Guided Notes
Key concepts students will learn:
- •
Igneous rocks are formed from hot molten rock that cools and solidifies from either magma or lava.
- •
Extrusive igneous rocks form on the surface, cool quickly, and have small or no crystals, while intrusive rocks form inside the Earth, cool slowly, and have larger crystals.
- •
Igneous rocks can be classified as either mafic, which are dark in color and contain magnesium and iron, or felsic, which are lighter and contain feldspar and silica.
