🔍 Key Concepts

• Coriolis force and hemisphere – how moving water is deflected in the Northern vs Southern Hemisphere • Latitude effect – where on Earth the Coriolis force is strongest vs weakest • Depth and friction – how surface vs deeper water respond to forces and friction

💭 Think About

• Think about how winds and currents curve on weather maps in the Northern Hemisphere – do they bend right or left relative to their motion? • Ask yourself: is the Coriolis effect zero, small, or large at the equator? How does it change as you move toward the poles? • Consider whether friction with the sea surface and bottom would make Coriolis more noticeable in shallow or deep water.

✅ Before You Answer

• Be sure you know in which direction moving objects are deflected in the Northern Hemisphere. • Recall that the magnitude of Coriolis depends on latitude, not on depth. • Consider whether greater depth increases Coriolis itself, or just changes how the water column responds to it.
