The TEKS Know that climatic interactions exist among Earth, ocean, and weather systems. 8.10 (A) recognize that the Sun provides the energy that drives convection within the atmosphere and oceans, producing winds and ocean currents;
ENGAGE Ocean Currents What causes the movement of air and water throughout the Earth?
EXPLORE 1) Fill your container with tap water. 2) Carefully place blue water at each end of the container using a syringe. 3) Observe what happens. 4) Record your observation on your lab sheet.
EXPLAIN 1) What did the blue water represent? 2) Why was the blue water placed at the far end of your container? 3) What did you observe?
TIME FOR A FOLDABLE CONVECTION Transfer of heat by the movement of warmer, less dense (air or liquid) rising and cooler, denser (air or liquid) sinking
CONVECTION CONVECTION CONVECTION Moves air in the atmosphere! Moving Air = Winds
Convection in the atmosphere is the main cause of the wind. Where does the Energy for Convection come from on Earth? THE SUN!!!
CONVECTION CONVECTION causes deep ocean currents! CONVECTION
Wind over the shore changes direction because of EARTHS UNEVEN WARMING &
COOLING! Hot Air is Less Dense! Atmospheric Movement MOSTLY CAUSED BY:
- Temperature differences - Pressure differences - Coriolis Effect (due to Earths rotation) The Coriolis effect The Coriolis effect
Is a result of Earths rotation Causes moving objects to follow curved paths: In Northern Hemisphere, curvature is to right In Southern Hemisphere, curvature is to left Changes with latitude: No Coriolis effect at Equator
Maximum Coriolis effect at poles The Coriolis effect on Earth As Earth rotates, different latitudes travel at different speeds
The change in speed with latitude causes the Coriolis effect Figure 6-9a Role of the Ocean
Slowly absorbs and slowly releases heat energy helping keep Earths temperatures relatively stable Oceans heat or cool the air above them and transport heat around the globe in currents. Hurricanes form over warm ocean
water, drawing their energy from the waters heat. Ocean Currents Currents
large scale water movements occur everywhere in ocean both surface and deep 2 main types: surface currents (10%) and deep sea currents (90%)
surface currents are primarily wind driven deep currents are density driven other forces affecting currents Coriolis effect friction gravity thermal expansion
geologic shape of ocean basin ELABORATE 1) Use the pipette to carefully put several drops of red hot water at the bottom of the container.
2) Remove the pipette and watch what happens to the red water. Why is it important to study ocean currents? How do plants, animals, and humans
use ocean currents? Ten Bizarre Things That Washed Up On Shore EVALUATION 1) Convection currents, which affect weather and climate, are created by...

4. Which of the following is NOT true: A. colder, denser water at the poles sinks below warmer water. B. colder, denser water at the poles rises above warmer water. C. warmer, less dense water at the
equator rises above colder water. D. saltier, denser water sinks below fresh, less dense water. 4. Which of the following is NOT true: B. colder, denser water at the poles rises above warmer water.
5. What does the Coriolis Effect explain? A. why it is hard to catch baseballs. B. why surface winds or currents turn in one direction or another. C. how volcanoes are formed. D. why salt water is denser than
fresh water. 5. What does the Coriolis Effect explain? B. why surface winds or currents turn in one direction or another.
