Goals for this lab
 Learn the basics of

rock identification
 Learn how to distinguish between 3 rock types
 Observe hand samples and infer how they
might have been formed


*Solid aggregate of mineral grains, mineral
crystals, or other rocks
*Some exceptions
**Obsidian is made of volcanic glass
**Coal is made of plant fragments
*The materials forming rocks come from the
Earth’s mantle as magma, from space, from
organisms, or from the breakdown of other rocks
and minerals.


*Environmental changes and processes affect the
rock forming materials and existing rocks
*These changes and processes produce 3 distinct
groups of rocks
**IGNEOUS
**SEDIMENTARY

**METAMORPHIC
