Ocean gyres are large systems of circular ocean currents. On the map, they are outlined by the arrows that represent the direction of the ocean current, and whether that current is warm or cool. The world's five major garbage patches include the North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific. These garbage patches are labeled on the map.
Garbage Patches form in the center of major gyres.

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

Transcript:

When the wind blows along the coastside, it drives the surface layer of the sea. But due to the Coriolis effect, the surface water layer is deflected away from the coast. That surface layer also drives the one located just below it ... which is also deflected offshore due to Coriolis effect.

And so on...

That results in a net offshore mass transport in the upper layers of the sea.

To counteract this mass transport; cold water rises from the depths. This mineral-rich water delights phytoplankton, and therefore, delights zooplankton, fish, ... and fishermen!

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

Describe how deep ocean trenches form, explain plate tectonics in detail, and compare tectonic activity between continents.

Memorize names and locations of all major ocean currents and list marine species found in each region

Explain how wind and Earth's rotation (the Coriolis effect) move surface currents, read maps to tell wind/current directions and spin, identify where trash collects in gyres, and predict where upwelling will occur.

Calculate global sea level rise from melting ice using complex climate models without interpreting maps or ecological impacts.

Reflect on your understanding of the learning objectives:

	Describe how wind patterns and the Coriolis effect drive surface ocean currents
	Analyze maps and diagrams to explain how ocean gyres form and why garbage patches collect in the center of these circular currents.

Reflect on your mastery of the success criteria:

	Identify that winds push surface currents in the same direction, describe that currents rotate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere, and explain the Coriolis effect causes this rotation.
	Analyze maps and diagrams to explain how ocean gyres form and why garbage patches collect in the center of these circular currents.

Predict: Who will catch the ball?

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?
