1. Early Finisher Tasks
If you finish your work early, you may select one of the two books from the basket. 1.) Earth: The Inside Story 2.) The Shaping of the Continents Read the short stories. Then, turn to the back cover and answer the “Reader Response.” There are four questions per story.

2. Plate tectonics
In Tennessee, we are blessed with the Great Smokey Mountains. How could these mountains have formed?
SPI

3. Learning target
I can describe internal forces such as faulting and plate movements that are responsible for the Earth’s major geological features such as mountains and valleys.

4. Vocabulary
Core: the central part of Earth; it is composed of a liquid outer core and a solid inner core

5. Vocabulary
Mantle: the thick layer of solid and molten rock that lies around the core; it is divided into two parts-the lower and upper mantle

6. Vocabulary
Crust: the thin layer of solid rock that makes up the outermost part of Earth

7. Vocabulary
Hydrosphere: all of Earth’s liquid and solid water-including oceans, lakes, rivers, glaciers, and the water located underground
The Greek word “hydro” means water, and the Greek word “sphere” means globe.

8. Brainstorm different geological features you have seen.
Vocabulary
Geological Features: a physical structure on Earth’s surface
Brainstorm different geological features you have seen.

9. Vocabulary
Plate tectonics: a theory that explains that Earth’s crust are made of moving plates

10. Vocabulary
Magma: hot, melted rock

11. Vocabulary
Fault: a break or crack in the rock of the lithosphere along which movements take place; faults are the site of many powerful earthquakes

12. What are earth’s layers?
1.) The center part of Earth is made up of two parts the molten outer core and the solid inner core.

13. What are earth’s layers?
2.) The layer above the core is called the mantle.

14. What are earth’s layers?
3.) Continents and the ocean floor are part of Earth’s solid, rocky surface called the crust.

15. Quick Check
Independently label the different layers of Earth’s crust.

16. Quick Check
With your partner, discuss this question. Be prepared to share your partner’s thoughts. “From which layer of Earth do people get most of their resources? Why do you think that?”

17. Are the continents moving?
4.) Alfred Wegener stated that Earth’s continents were once joined in one landmass, but gradually pulled apart and drifted.
Wegener was a geologist, which is a scientist that examines rocks to find out about Earth’s history and structure.

18. Are the continents moving?
5.) Wegener’s research showed that the age and composition of rocks in the mountains on South America’s east coast matched of those on Africa’s west coast.
His idea became known as the theory of continental drift.

19. Are the continents moving?
6.) Scientists also discovered evidence in fossils that Africa and South America were once joined.

20. Quick Check
Parts of this video are made up, and parts are based on science. Can you connect anything in the video to something you may have learned in the previous slides? Be prepared to share!

21. Quick Check
What caused scientists to conclude that Earth’s continents were once joined?

22. What causes the ocean floor to move?
7.) Scientists developed the plate tectonics theory to explain how the continents have moved over millions of years.

23. What causes the ocean floor to move?
8.) Earth’s lithosphere is made of huge pieces of solid rock called plates. 9.) Melted rock called magma rises up through the crack where plates move apart under the ocean.

24. What causes the ocean floor to move?
10.) As the ocean floor spreads at the plate boundary, the continents resting on the plates also move apart.

25. What forces change Earth’s crust?
11.) The force that causes rocks to break as plates rub past each other is called shearing.

26. What forces change Earth’s crust?
12.) A break or crack in the rocks of the lithosphere along which movements take place is called a(n) fault. 13.) Three types of faults include a strike-slip fault, a(n) normal fault, and a reverse fault.

27. What forces change earth’s crust?
With your group, you will read the information on page 203 about the fault you are assigned. Then, using the material provided, you will describe the fault with words and visuals. You will be responsible for teaching the rest of the class about your fault. You have 10 minutes!

28. What are the different types of Mountains?
14.) When plates push together, compression causes the ground to form folded mountains.

29. What are the different types of Mountains?
15.) A mountain range in Asia, the Himalayas began to form millions of years ago as folded mountains.

30. What are the different types of Mountains?
16.) When rock on one side of a fault moves down and rock on the other side moves up, a fault-block mountain is formed.

31. Quick Check
17.) Compare how two types of mountains are formed.
