Objectives

Describe how wind patterns and the Coriolis effect drive surface ocean currents
Analyze maps and diagrams to identify wind and surface current directions, determine rotation (clockwise vs. counterclockwise), evaluate gyre-driven debris accumulation (garbage patches), and predict regions of upwelling.

Geography Review

A hemisphere is half of Earth. An imaginary line divides Earth into two equal halves:

The Equator splits Earth into the Northern Hemisphere (above the Equator) and the Southern Hemisphere (below the Equator).
An imaginary line through the poles (the Prime Meridian and the 180th meridian) splits Earth into the Eastern Hemisphere (east of the Prime Meridian) and the Western Hemisphere (west of the Prime Meridian).

Label the hemispheres highlighted in the image below.

Geography Review

Names & locations of the world's oceans

Pacific Ocean: Largest; stretches between the Americas (east) and Asia/Australia (west).
Atlantic Ocean: Between the Americas (west) and Europe/Africa (east); connects north and south via the equator.
Indian Ocean: South of Asia, between Africa (west) and Australia (east).
Southern (or Antarctic) Ocean: Encircles Antarctica; southernmost ocean surrounding the continent.
Arctic Ocean: Smallest; located around the North Pole, bordered by northern North America, Greenland, and Eurasia.

Label the oceans on the map.

Remember that the Earth is a globe, so oceans wrap around and cross the map edges of a flat map.

Will plastic released from different areas of the same continent end up in the same place(s)?

Go to the Plastic Adrift website to test various locations or watch the videos below.

Consider plastic being released from Peru on the west coast of South America:

Then consider plastic being released from the same continent, but now at the southern tip of Chile:

Did plastic released from different areas of the same continent end up in the same place(s)?

Because the camerawork distorts the ball's path

Because the ball actually follows a curved path through the air

Because the table (merry‑go‑round) moves under the ball, changing who is in front of it

In 1992, a cargo ship carrying bath toys got caught in a storm. Shipping containers washed overboard, and the waves swept 28,000 rubber ducks into the North Pacific Ocean.
What could explain how the rubber ducks were transported around the world?

Thinking Question: What happens when surface currents run into the coast of a continent?

In this scenario, what drives the surface layer of the sea?

Which of the following best re-states this assignment's learning objectives?

While the merry-go-round is rotating counterclockwise, the students throw the ball "straight" across.
According to the video, why does the ball appear to curve to an observer on the merry‑go‑round?

What is marine debris?

What is the most common item found in marine debris?

All marine debris is visible.

What is a garbage patch?

Why can't we simply scoop up all of the marine debris from the garbage patch?

Which method is most effective for addressing ocean garbage patches?

In this scenario, what drives the surface layer of the sea?

What causes the surface water layer to be deflected away from the coast?

What is the result of this deflected surface water?

Why is upwelling important for both marine ecosystems and coastal economies?
