2. Can you guess what country this is?
How many “regions” do you see?
Coastal Plains
Interior Lowlands
Great Plains
Basin and Ridge
Appalachian Mountains
Rocky Mountains
Coastal Ridge

3. What stands out on this map?
Now, what do you see?
What stands out on this map?

4. Which words do you know, and which do you need help with?
Tectonic Forces
Earthquake
Tsunami
Volcano
Spreading
Building
Lithosphere
Subduction
Mountain

5. How do “tectonic forces” affect a region?
THE HESS CONVECTION CURRENT ‘SLAB-PULL’- ‘RIDGE PUSH’ MODEL
Continents pushed apart by ‘Ridge-Push’
Subduction of oceanic Crust by ‘Slab Pull’
Magma
Ridge-Push by diverging convection currents
Subduction by converging convection currents
Continental Crust pulled over the Oceanic Crust
LITHOSPHERE
(Tectonic means “building” The earth is “building” itself by building its lithosphere)
Describe what you see in the diagram

6. How do “tectonic forces” affect a region?

7. How does “erosion” affect a region?
WATER
WIND
DESCRIBE WHAT’S HAPPENING TO THE LAND
SOIL
GRAVITY

8. How does “weather” affect a region?
DESCRIBE WHAT’S HAPPENING TO THE LAND

9. How does a region affect the weather?
“Orographic” Effect -- Greek: Oro-- Hill, Graphic-- Write
Hill writing. The hill writes its effect on the weather.

10. Where would the “orographic effect” be most likely?
Coastal Plains
Interior Lowlands
Great Plains
Basin and Ridge
Appalachian Mountains
Rocky Mountains
Coastal Ridge

11. Let’s see what we know… Which are you ready to answer, and which do you need a peek?
Tectonic plate movement may be caused by all of the following EXCEPT— A slab pull B ridge push C convection D magnetism
All of the following are tectonic forces that shape the surface of the earth EXCEPT— A subduction B spreading C transformation D transpiration

12. A erosion B tectonic forces C deposition D weathering
Let’s see what we know… Since you could answer the last question, can you answer this one?
The Middle East consists of mountains, upland plateaus and valleys. These physical features are the result of:
A erosion
B tectonic forces
C deposition
D weathering

13. The same tectonic force, many continents…
Let’s look again at “Tectonic Forces”
The same tectonic force, many continents…
THE HESS CONVECTION CURRENT ‘SLAB-PULL’- ‘RIDGE PUSH’ MODEL
Continents pushed apart by ‘Ridge-Push’
Subduction of oceanic Crust by ‘Slab Pull’
Magma
Ridge-Push by diverging convection currents
Subduction by converging convection currents
Continental Crust pulled over the Oceanic Crust
LITHOSPHERE
(Tectonic means “building” The earth is “building” itself by building its lithosphere.)

14. Let’s see what we know… Which are you ready to answer, and which do you need a peek?
Because of its location along the "Ring of Fire," Japan is particularly susceptible to which of the following hazards? F earthquakes and volcanoes G floodings and droughts H monsoons and floodings J earthquakes and tornados
The Pacific Islands in the Ring of Fire are affected by all of the following except — A volcanoes B earthquakes C tsunamis D tornadoes

15. Talk to each other, and then talk to me…
