Rock Unit Concept Map
Directions: Use the following words to make a graphic organizer/Concept Map. Try to arrange
the words into similar groups first, and then decide how they are related. Start with big ideas,
and branch your way down to smaller ideas. For example, Start with rock families, then break
that into 3 groups (Metamorphic, Sedimentary, Igneous) Then you will break each of the
families down. You will be responsible for all of these words on the test. Underlined words do
not have to be included, but may be extra credit questions on test.
