2. Marine Science Unit 2: Origins of the Ocean and Global Geography
By Mrs. Moreaux and Mrs. Shaw

3. Unit 2: Origin of the Ocean and Global Geography Learning Goals
Students will be able to
Explain the origin of the Earth and it’s ocean.
List and locate the 5 main oceans and 7 continents.
Use proper coordinates such as latitude and longitude to locate specific locations on a global map.

4. The Origin of the Earth and it’s Ocean
Part 1
The Origin of the Earth and it’s Ocean

5. How did the Earth form?
Our solar system formed from a solar nebula, a cloud of gas and dust, that collapsed and condensed about 4.56 billion years ago.
Most of the matter formed the Sun but the rest formed the planets and other bodies in our solar system

6. The Young Earth
Scientists study meteorite materials to discover what materials were first present on Earth that eventually were recycled into Earth’s crust.
The young Earth was anything but habitable. Radioactive elements decaying within its mass and impacts from debris raining down from space generated intense heat—the first eon of Earth's history, from about 4.5 to 3.8 billion years ago, is named the Hadean after hades, the Greek word for hell
The Willamette Meteorite, the largest ever found in the United States (15 tons)

7. How do we know that the cloud of gas and dust turned into our star, the Sun, and planets?
The Universal Law of Gravitation – everything with mass has gravity and is attracted to everything else with mass.
Where is our evidence of this??
2:95- 9:54

8. Reminder . . . a scientific law if usually associated with a mathematical equation.

9. About 4 billion years ago
About 4 billion years ago, conditions on Earth gradually began to cool. The planet's surface cooled, enough to allow water vapor to condense in the atmosphere and fall back as rain. This early hydrologic cycle promoted rock weathering, a key part of the carbon-silicate cycle that regulates Earth's climate

10. How did the Ocean form?
Condensing water vapor, along with ice delivered by comets and water trapped in meteorites, accumulated in the atmosphere and cooled the molten exterior of the planet to form a solid crust and produced the oceans. This period ended roughly 3.8 years ago with the onset of the Archean age, by which time, the Earth had cooled significantly and primordial life began to evolve.

11. The Beginning of Oceans and Life!
How the Earth was made

12. Opening Assignment
Review your notes on the origin of the Earth and it’s Ocean and explain in your own words what happened when the Earth and it’s ocean was formed.

13. Global Geography of the Earth’s Oceans and Continents
Part 2
Global Geography of the Earth’s Oceans and Continents

14. In order to study the oceans, we need to know where they are!
In PENCIL: Label the 5 oceans and the 7 continents on your blank world map.

15. Arctic
North America
Europe
Asia
Atlantic
Africa
Pacific
South America
Indian
Australia
Southern
Antarctica

16. The oceans are so vast . . . so how do we keep track of specific locations?
Latitude & Longitude
Measured in degrees, minutes and seconds
Ex. Vero Beach is
Latitude: 27° 38' 17" N 27 degrees, 38 minutes, 17 seconds North
Longitude: 80° 23' 51" W 80 degrees, 23 minutes, 51 seconds West
TODAY WE WILL ONLY MEASURE THE DEGREES 

17. Latitude Lines of latitude run West - East The Equator is latitude 0°
Latitude coordinate is always listed first, and followed by
N or S

18. Longitude Lines of longitude run North-South
The Prime Meridian is Longitude 0°
Longitude coordinate is always listed second, and followed by E or W

19. NORTH
EAST
WEST
SOUTH

20. Practice Using the map provided plot the following points:
15° N, 90° W
75° S, 75° W
45° N, 135° E
60° S, 105°E

21. Check your map 
NORTH
EAST
WEST
SOUTH

22. Homework – Locate the following on your map and list the coordinates
Caribbean Sea
Gulf of Mexico
Mediterranean Sea
Bering Sea
Red Sea

23. Homework ANSWERS – Locate the following on your map and list the coordinates – ARE APPROXIMATE
Caribbean Sea 15° N, 70° W
Gulf of Mexico 30° N, 90° W
Mediterranean Sea 35° N, 15°E
Bering Sea 65° N, 170°W
Red Sea 20° N, 40°E

24. Check your map 
NORTH
EAST
WEST
SOUTH

26. Opening Assignment
