• http://www.pbslearningmedia.org/resource/ess05.sci.ess.earthsys.tectonic/tectonic-plates-earthquakes-and-volcanoes/

• Plate Tectonics- An Introduction

• Lithosphere-solid part of Earth (upper mantle and crust)

• Hydrosphere-liquid part of Earth

• Coastlines, water depth & sediment type are affected by the constant movement of continents and rocks

World Ocean

4 Basins– Pacific – Atlantic– Indian– Arctic

Layers of Earth• The Core- innermost iron rich layer-a

solid inner & a liquid outer–Movement of liquid produces the

Earth’s magnetic field• The Mantle- outermost solid layer

–Extremely hot–Boiling point for rock–Flows like liquid but very slow

Crust-thin skin like layer

• Oceanic Crust– 3 miles thick– Sea floor– Basalt- a dark colored mineral– Denser

• Continental Crust– 10-30 miles thick– Granite- a light colored mineral

• **Think of continental & oceanic crust floating on mantle like icebergs

• Continental Crust- land• Continental Shelf- gradual decline• Continental Slope- sharp decline• Continental Rise- levels out to meet sea floor• Abyssal Plain/Deep Ocean

Narrow Shelf Wide Shelf

• Alfred Wegener– 1912- Continental drift was proposed

• 1950’s-1960’s- evidence was found & called Plate Tectonics– Geologic change is CONSTANT– Fossil, coal deposits, etc is evidence of

joined continents.– This large land mass is known as Pangaea

Seafloor Spreading Support

• Go to these sites and read the article then in your notebook on pg. 80

• Summarize the main idea and why the Glomar Challenger and Alvin are important to the Plate Tectonics Theory. Give A LOT of support!– http://www.divediscover.whoi.edu/history-

2. Divergent

3. Transform

DISCUSSION QUESTIONS

1. What happened to the frosting between the crackers?

2. What do the graham crackers represent?3. What does the frosting represent?4. Name a specific location on the Earth where this kind

of boundary activity takes place.5. What type of feature is produced by this movement?6. What is the process called that creates new ocean

floor from diverging plates?

7. What happens when a tectonic plate gets subducted?

8. Name a specific location on the Earth where this kind of boundary activity takes place.

9. What features are formed on the continent along this boundary?

10.What feature is formed in the ocean along the subduction zone?

11.What happens to the wet ends of the graham crackers?

12.In what way do the wet crackers act more like the real crustal plates than the dry crackers?

13.What feature do the resulting ends of the wet crackers represent?

14.Name a specific location on the Earth where this type of boundary activity takes place

15.Why is this movement often described as “horizontal” sliding?

16.Name a specific location on the Earth where this type of boundary activity takes place.

17.Nothing happens at the beginning, but as the pressure is increased, the crackers finally break. What do we call the breaking and vibrating of the Earth’s crust?

CONCLUSION:

1. Give an example of how plate movement directly affects the construction of Earth’s surface.

2. Give an example of how plate movement directly affects the destruction of Earth’s surface.
