Click next to go to the Rock Cycle Diagram – scroll down and follow instructions for # 1, 2, & 3.
Interactive Rock Cycle http://www.learner.org/interactives/rockcycle/
1. What are the 3 main types of rocks? How is each one formed?
2. Copy the chart; do not have to include pictures.
3. Follow directions at bottom of page to start your rock collection. Write a brief explanation
about each rock, and then add it to your collection.
4. At bottom of page, click on “Identify Rock Types.” Follow directions at end of quiz to go to
“How Rocks Change.”
5. Discuss each process that enables a rock to change from one type to another.
Continue to click next. At the bottom of “Weathering and Erosion” page, click on the first
“Transform the Rock” phrase. Be sure to actually read and jot down important information.
Go to the “Rock Cycle Diagram”.
6. List e examples of each type of rock.
7. Draw the diagram.
8. Click on “Complete the Cycle”; do exercise
9. Go to Test Your Skills. Put your full name. When you have completed the test, print and
hand in to teacher.
Igneous rocks http://www.arch.dcr.state.nc.us/ncarch/GeoArcheo/IgneousA.htm
1. Use a Venn diagram to compare and contrast the two types of igneous rocks.
2. What properties are used to identify igneous rocks/
3. Explain the difference between a felsic mineral composition and a mafic mineral
composition.
4. How is the texture of an igneous rock determined?
5. Why does the type of mineral composition matter when identifying an igneous rock?
6. How is the grain size of an igneous rock determined? Explain your answer.
Sedimentary rocks http://geology.about.com/cs/basics_roxmin/a/aa011804b.htm
1. Why are sedimentary rocks called stratified rocks?
2. Create a chart and discuss the three types of sedimentary rocks.
Metamorphic rocks http://www.mineralogy4kids.org/?q=rock-cycle/metamorphic-rocks
1. What does the term, “metamorphic” mean?
2. Changes in temperature and pressure causes minerals to do what in a rock?
3. List the two types of textures for metamorphic rocks. Explain each one. How are they
identified?
4. Give 3 examples of foliated metamorphic rocks and 2 examples of nonfoliated
metamorphic rocks.
Moh’s Scale http://www.allaboutgemstones.com/mohs_hardness_scale.html
11. What is Moh’s Scale used for?
12. What mineral is a 10 on Moh’s Scale?
13. Give an example of a mineral with a hardness of 7 (according to Moh’s Scale). Tell me
about that mineral.
14. If a mineral can scratch a penny, what number is it on Moh’s Scale?
