1. SC.912.E.6.5
Describe the geologic development of the present day oceans and identify commonly found features.  

2. Earth Structures - The scientific theory of plate tectonics provides the framework for much of modern geology. Over geologic time, internal and external sources of energy have continuously altered the features of Earth by means of both constructive and destructive forces. All life, including human civilization, is dependent on Earth's internal and external energy and material resources.

5. QUESTIONS
According to the plate tectonic theory, when oceanic plates collide with continental plates, the denser oceanic plate is forced under the lighter continental plate. Which geologic feature is a result of this type of collision?
F. hot spot
G. abyssal plain
H. midocean ridge
I. composite volcano

6. DAY 1 What are the three main regions of the ocean floor?
How do the continental margins in the Atlantic Ocean differ from those in the Pacific Ocean?

7. Key Vocabulary Continental margin Ocean Basin Floor Mid-Ocean Ridge
Zone of transistion between continent and adjacent ocean
Ocean Basin Floor
Between the continental margin and mid-ocean ridge
Mid-Ocean Ridge
Found near the center of most ocean basins

8. Label the three main regions: Continental Margin, Ocean basin Floor, Mid- Ocean Ridge

9. 14.2 Ocean Floor Features Mapping the Ocean Floor
 The ocean floor regions are the continental margins, the ocean basin floor, and the mid-ocean ridge.

10. 14.2 Ocean Floor Features Continental Margins
 A continental margin is the zone of transition between a continent and the adjacent ocean basin floor.
 In the Atlantic Ocean, thick layers of undisturbed sediment cover the continental margin. This region has very little volcanic or earthquake activity.

11. Atlantic Continental Margin

12. 14.2 Ocean Floor Features Continental Margins
 In the Pacific Ocean, oceanic crust plunges beneath continental crust. This force results in a narrow continental margin that experiences both volcanic activity and earthquakes.

14. The Continental Margin
VOCABULARY
The continental margin is the underwater edge of a continent. It includes the continental shelf, continental slope, and continental rise, as well as submarine valleys and canyons.

Sediment
Continental slope
Abyssal plain

15. DAY 2
How do the Atlantic and the Pacific Ocean differ?

16. 14.2 Ocean Floor Features Ocean Basin Floor
 The ocean basin floor is the area of the deep-ocean floor between the continental margin and the oceanic ridge.
 Deep-Ocean Trenches
Trenches form at the sites of plate convergence where one moving plate descends beneath another and plunges back into the mantle.

17. 14.2 Ocean Floor Features Ocean Basin Floor  Abyssal Plains
An abyssal plain is a very level area of the deep-ocean floor, usually lying at the foot of the continental rise.
The sediments that make up abyssal plains are carried there by turbidity currents or are deposited as suspended sediment settles out.
 Seamounts and Guyots
A seamount is an isolated volcanic peak that rises at least 1000 meters above the deep-ocean floor, and a guyot is an eroded, submerged seamount.

18. Abyssal Plain Cross Section

19. The Ocean Basin
Coral reefs can form around volcanic islands. As the islands sink with the ocean crust, rings of coral are left behind which continue to grow, forming barrier reefs and atolls.
Barrier Reef
Atoll

20. How would a profile of the pacific Ocean basin differ from the profile of the Atlantic Ocean?
Pacific Ocean does not show a central mid ocean ridge. Instead, depending on how the transect line is drawn, it would show trenches, chains of volcanic islands or coral atolls

21. DAY 3 What is formed at the mid-ocean ridge?
Create a Venn Diagram to compare/ contrast the two.
New ocean floor is formed at the midocean ridge
Seafloor spreading and hydrothermal vents occur where magma rises up from below the earths crust. Both occur at mid ocean ridge. One is new magma and the other is deposits from the water

22. Ocean Floor Features Mid-Ocean Ridges
 A mid-ocean ridge is found near the center of most ocean basins. It is an interconnected system of underwater mountains that have developed on newly formed ocean crust.
 Seafloor Spreading
Seafloor spreading is the process by which plate tectonics produces new oceanic lithosphere at ocean ridges.
New ocean floor is formed at mid-ocean ridges as magma rises between the diverging plates and cools.

23. 14.2 Ocean Floor Features Mid-Ocean Ridges  Hydrothermal Vents
Hydrothermal vents form along mid-ocean ridges. These are zones where mineral-rich water, heated by the hot, newly-formed oceanic crust, escapes through cracks in the oceanic crust into surrounding water.

24. What is formed at the mid-ocean ridge?
Create a Venn Diagram to compare/ contrast the two.
New ocean floor is formed at the midocean ridge
Seafloor spreading and hydrothermal vents occur where magma rises up from below the earths crust. Both occur at mid ocean ridge. One is new magma and the other is deposits from the water
