Ocean Currents What Are Currents? Current: a large stream of moving water that flows through the oceans. Currents carry water over very long distances.

Ocean Currents Streamlike movements of water.. Surface Currents Streamlike movements of water that occur at or near the surface of the ocean.

Ocean Currents. Ocean currents are streams of water that can move millions of cubic meters of water per second. Ocean currents are streams of water that.

Atmospheric movements We learned that energy is transferred from the Sun to the Earth creating convection currents. But, what type of currents???

Ocean Currents.

Mrs. Mannel Earth Science. Surface Currents  Surface currents move water at or near the surface in stream like movement  They can be several thousand.

Ocean Currents. Mass movement or flow of ocean water Mass movement or flow of ocean water River within the ocean River within the ocean Two types Two.

Catalyst (5 minutes) Use your homework from last night: Describe the waters of a deep current. What two continents does the Gulf Stream warm? What is the main cause of surface currents?

January All-Star Scholars Space Unit Super Star Scholars Congratulations!!! January All-Star Scholars Space Unit Super Star Scholars Antonio Bean Tia Love Dominique Jamison Raven Ferguson Michael Hargrove These scholars had no missing assignments in the third grading period and have been working hard to get smart everyday! Marquavious Moore Rodrigo Araujo Nicole Lay Garrett Ross Travius Winfrey Akil Purdy Our next meeting will be this Friday, February 18th at lunch.

Deep Currents Streamlike movements of ocean water far below the surface.

Understanding the causes of currents: Working with a Partner Using the chapter section we just read about, answer the following questions on your Cornell Notes with a partner List the three factors that cause surface currents. List the three factors that cause deep currents. How are surface currents and deep currents different?

3 factors that cause Surface Currents (1) Global winds (2) The Coriolis Effect (3) Continental deflections These three factors keep surface currents flowing in distinct patterns around the Earth.

3 factors that cause Deep Currents (1) Decreasing temperatures (2) Increasing salinity through freezing (3) Increasing salinity through evaporation.

Brain Pop Video: Ocean Currents Think about the following questions. Then during the discussion of the video, write down your answers! What is the main force that drives surface currents? What causes the Coriolis Effect? The Gulf Stream delivers warm water to what region? What happens to the warm water carried by the Gulf Stream? What happens to warm ocean water when its loses heat energy? What is the system of deep and shallow currents that circles the earth called? How does it take ocean water to travel completely around the Earth?

The effect of the Coriolis effect In what direction do currents move in the Northern Hemisphere? In the Southern Hemisphere?

Making your own map of Surface Currents Using the colored map of surface currents, highlight your own map to show the warm and cold currents of the world! Take a blue and red marker or colored pencil, and highlight the arrows: Red: Warm Currents Blue: Cold Currents

What best describes the movement of water in the Gulf Stream?

Finding Nemo What current are all of the sea animals traveling in? Describe the current you see in the movie – what is it like? Find the current on your map from yesterday!

Homework tonight Homework worksheet: Exploring Our World’s Currents Make a list of all the world’s currents Northern Hemisphere: Warm Currents Northern Hemisphere: Cold Currents Southern Hemisphere: Warm Currents Southern Hemisphere: Cold Currents Then, using the names of the currents and your knowledge of them, plan a trip around the world!
