1. Classifying Rocks
Rocks are classified by how they formed and what they’re made of
There are 3 general classes of rocks
Igneous Rocks…are formed when lava and magma crystallize to form solid rock
Metamorphic Rocks…are formed when an existing rock is partially melted, squeezed, or both
Sedimentary Rocks…are formed when sediments (sand clay, and silt) are compressed and become solid rock
