How to classify rocks!
When Classifying rocks you do it by the type of rocks they are. There are three types of rocks Igneous, sedimentary, and metamorphic. Igneous rocks are formed by lava and magma, sedimentary rocks are formed by the processes of erosion, deposition, compaction, and cementation and metamorphic rocks are formed by heat and pressure deep under the earth surface changing the rock.
Classifying rocks can be hard and it takes practice. But with practice and training you can do it.
