Vocabulary Words You Need to Know:
(Students who make and show flash cards with definitions on the back for all 37 vocabulary words will receive 5
points extra credit on their test. I suggest students keep their flash cards in a box to use at the end of the year to
study for the Milestones testing.)

Know and be able answer the following questions;
1. What is a mineral and how is it identified? Be familiar with key mineral characteristics like
streak, luster, cleavage and Moh’s hardness scale.
2. What is a rock? How is it different from a mineral?
3. What are the 3 different types of rocks? Be able to explain how each one is formed (the
process) and be able to give examples of each one.
4. What is the difference between extrusive and intrusive igneous rocks? (Know the
difference in grain/crystal size.)
5. How do scientists use fossils to better understand how the earth has changed over time?
6. What is a mid-ocean ridge? Why would the youngest rocks on the ocean floor likely be
found at the mid-ocean ridge?
7. What can we tell about the age of a fossil based upon the depth in the earth it is found?
