Light-colored igneous rocks are less ______________________ than Skills dark-colored igneous rocks are 5. Light-colored igneous rocks that are rich in aluminum, potassium, silicon, and sodium are called ______________________ rocks. 6. Dark-colored igneous rocks that are rich in calcium, iron, and magnesium are called ______________________ rocks. 7. The longer it takes for a rock to cool and solidify, the more time ______________________have to grow, giving the rock a(n) ______________________ grain. 8.
