Minerals & Rocks
Rocks: (chapter 3)• The rock cycle shows how rocks
change• Igneous rocks form from molten rock• Sedimentary rocks form from earlier
rocks• Metamorphic rocks form as existing
rocks change
Minerals are everywhere!!!• 4000+ identified minerals in Earth’s crust
• Minerals = building blocks of rock

Igneous rocks form from molten rock.3.23.2
extrusive igneous rock
intrusive igneous rock
As molten rock cools, minerals crystallize and form igneous rocks.
Extrusive igneous rocks cool quickly at Earth's surface.
Intrusive igneous rocks cool slowly within Earth.
3.33.3 Sedimentary rocks form from earlier rocks.
